This study presents a comparative analysis of different proportional-integral (PI) controller tuning methods for the control of a non-interacting liquid level process. Four different PI controller tuning methods, Ziegler-Nichols, Cohen-Coon, Tyreus-Luyben, and Internal Model Control, are evaluated based on their ability to track setpoint changes and reject disturbances. The simulation results show that all four tuning methods can provide satisfactory performance, but the Internal Model Control method outperforms the others in terms of all performance metrics evaluated. The Ziegler-Nichols method produces the worst performance, while the Cohen-Coon and Tyreus-Luyben methods perform better but still have limitations. This study highlights the importance of choosing the appropriate tuning method for liquid level control systems.

Abstrak- PT Pertamina Hulu Energi NSB dalam kegiatan produksinya banyak menggunakan peralatan-peralatan instrument dan lain-lain. Peralatan tersebut memegang peranan yang sangat penting guna untuk mendukung proses pengendalian. Salah satu pengendalian yang dilakukan pada PT PHE NSB adalah pengendalian level liquid pada knock out drum flare stack area. Knock out drum flare stack merupakan tangki yang menggunakan prinsip kerja gaya gravitasi. Ketinggian level yang ada pada tangki tersebut harus dijaga kestabilannya sesuai dengan setpoint yaitu 25%. Apabila liquid yang ada pada tangki melebihi dari nilai setpoint yang telah ditentukan, maka akan terjadi penguapan liquid yang menyebabkan kerusakan pada peralatan instrument lainnya. Untuk mengatasi masalah tersebut, dilakukan pemodelan matematis pada plant untuk mendapatkan fungsi alih menggunakan pengendali P, PI, PID dan dengan metode Ziegler-Nichols, Shinskey, Tyreus-Luyben. Hasil pengujian dari beberapa pengendali dan metode yang cocok digunakan untuk mengendalikan level pada knock out drum yaitu pengendali PI menggunakan metode Tyreus-Luyben dengan nilai Kp = 63,33 dan Ki = 11,52. Setting time (ts) yang dibutuhkan untuk mencapai nilai setpoint yaitu selama 2 menit dan tidak adanya overshoot maksimum.Kata kunci : Pertamina Hulu Energi NSB, Knock Out Drum, Level, Ziegler-Nichols, Shinskey, Tyreus-Luyben.Abstract- PT Pertamina Hulu Energi NSB in its production activities uses a lot of instruments and other equipment. The equipment plays a very important role to support the control process. One of the controls carried out at PT PHE NSB is controlling the liquid level on the knock-out drum flare stack area. A Knock-out drum flare stack is a tank that uses the working principle of gravity. The height of the level in the tank must be kept stable by the setpoint of 25%. If the liquid in the tank exceeds the specified setpoint value, there will be liquid evaporation which causes damage to other instrument equipment. To overcome this problem, mathematical modeling was carried out on the plant to obtain the transfer function using P, PI, PID controllers, and the Ziegler-Nichols, Shinskey, and Tyreus-Luyben methods. The test results from several controllers and methods that are suitable for controlling the level on the knock-out drum are the PI controller using the Tyreus-Luyben method with Kp = 63.33 and Ki = 11.52. The setting time (ts) required to reach the setpoint value is 2 minutes and there is no maximum overshoot.Keyword : Pertamina Hulu Energi NSB, Knock Out Drum, Level, Ziegler-Nichols, Shinskey, Tyreus-Luyben.

A B S T R A C TMilk cooling process is one of the most important milk processing steps after milk extraction process. Milk cooling process is carried out to inhibit the microbial growth. The milk is cooled from room temperature to 4 °C. Generally, this process is performed in batch installation. In this research, continuous milk cooling would be simulated. First, the model of the system was derived from the mass and heat balance. The simulation results were then identified using the System Identification Toolbox (SIT) on Matlab. System Identification Toolbox was used to build the mathematical models of dynamic system based on measured input and output data. The result of system identification is useful for setting control and stability analysis. The milk cooling system was then controlled by Proportional Integral (PI) Control. There are two kinds of tuning methods that will be analyzed. These are Hagglund-Astorm method and Tyreus-Luyben. The results showed that the control performance tuned using the Tyreus-Luyben method was better than the Hagglund-Astorm method from the criteria of its SSE (sum squared of error).Keywords: control; proportional integral; system identification; tuningA B S T R A KProses pengolahan susu yang sangat penting setelah pemerahan adalah proses pendinginan.

Nowadays, UAV quadcopters are widely used in many fields, specially in transporting the lightweight goods parcels. This article aims to design and evaluation of the quality of the 6-DOF UAV quadcopter control system using heuristic PID tuning methods to ensure stable control of flight position and attitude. Firstly, the article presents the dynamic mathematical model of the 6-DOF UAV quadcopter, including 3 Euler angle variables and 3 flight position and altitude variables. From there, the article proposes the 6-DOF UAV control syste structure with two single control loops for flight attitude, yaw angle and two dual control loops for roll-pitch angles, flight position. And then, the article presents the application of the heuristic PID tuning methods to each control loop of a 6-DOF UAV quadcopter to calculate the PID controller parameters to ensure stable control the desired flight position and altitude. The simulation results and evaluating the 6-DOF UAV quadcopter control system quality in Matlab, using the proposed heuristic PID controllers, show that the PID controllers according to the Tyreus-Luyben method gives the best quality, with a steady-state error of less than 1%. The main contribution of this article is the comparative analysis of three heuristic PID tuning methods - Ziegler-Nichols, Tyreus-Luyben, PID tuner - for controlling the position and attitude of a 6-DOF UAV quadcopter. These findings demonstrate that the proposed PID controllers can be effectively implemented in practical UAV applications, enhancing the stability and performance of quadcopters in various fields.

Refrigerator systems are used for food preservation as well as other applications. However, the cost of running the system is high due to rising fuel and electricity prices. Traditionally, these systems are controlled by On/Off controllers. This study proposes the use of a proportional-integral-derivative (PID) controller algorithm to reduce costs for domestic and industrial refrigeration without negatively affecting the system performance. To accomplish this, a physical model was developed, comprising a domestic refrigerator, microcontroller, and MATLAB computer software for analysis. A mathematical model of second-order lead and second-order lag transfer function was also developed for a typical refrigerator system. The physical model was connected, and open-loop temperature-time response data was collected for system modeling. In addition, Data were collected from industries namely Fan Milk Industry and Benue State University Teaching Hospital Mortuary for a robust system analysis. All data sets were imported into MATLAB's system identification toolbox to estimate model parameters. The ultimate gains, frequency, and period were determined for each feedback closed-loop model, allowing the application of Ziegler-Nichols and Tyreus-Luyben PID tuning settings. The closed-loop models were then simulated in MATLAB to evaluate system performance. Simulation results showed that the Tyreus-Luyben model performed better, and offered better temperature response, less undershoot, and faster settling time than the Zeigler-Nichols method. Both PID models outperformed the traditional On/Off controller, with energy consumption reduced to less than one-third of the conventional method. The study concludes that PID controllers are a better alternative to On/Off systems when properly tuned.

Because of its straightforward design and excellent adjustment efficiency, PID (proportional-integral-derivative) controllers are frequently employed in motor speed control. This study reviews the use of PID control technology in DC motor speed regulation, analyses DC motor speed regulation, and compares various proportional integral derivative (PID) speed regulation techniques. In this paper, the key role of PID parameter optimization in improving the response speed and accuracy of the system is analyzed and pointed out. The optimal technique for delivering a dynamic response to load disturbances and manageable overshoots is the modified Ziegler-Nichols modulation approach. The CHR regulation method is poor in dynamic response, while the Tyreus-Luyben regulation method is better in dynamic response to load interference, but the overshoot is small. Finally, the damped oscillation regulation method shows a higher stability time in the absence of overshoot. Proper proportional, integral and differential values of the tuned PID controller are essential for process control.

The temperature inferential control of an ideal hypothetical two feed two product ideal reactive distillation column is reported. The design of the column is an optimal one and the control structure consists of two temperature measurements with fixed reflux ratio policy. The transfer functions of second order relating the input and output variables of the temperature control loops are derived using the unit step responses under open loop. The tuning parameters for proportional-integral (PI) action are estimated using two optimization algorithms namely genetic algorithm (GA) and grey wolf (GW) algorithm. Minimization of integral time averaged error (ITAE) is the objective function for the optimization. Also, relay feedback method is used to estimate the ultimate gains and periods of the loops and the tuning parameters for PI action are calculated using Tyreus-Luyben (TL) settings. The closed loop dynamics of the column using the three sets of tuning parameters (GA, GW and TL) for throughput changes and feed impurity disturbances are compared. The tuning parameters estimated using GW are found to yield superior disturbance rejection characteristics for the RD column.

Power steering technology help human to control the car. The hydraulic power steering system now tends to be replaced by the electric power steering system (EPS). As the main driver that require precise control. The contribution of this research is to obtain system identification of EPS motor and novelty control strategy to achieve stable control better. Motor control require an appropriate mathematical model and up-down-up down signals of Pseudo Random Binary Signal Sequence (PRBS) were used. The modelling method used was the Numerical Algorithm for Subspace State Space System Identification (N4SID). The quality of the modeling needs to be measured to see whether it was close to the original signal. The validation of the model obtained tested using Variance Accounted For (VAC), Akaike Information Criterion (AIC), and Final Prediction Error (FPE). The best mathematical model was developed on the basis of these three criteria, which is 3rd order model. The control strategy carried out by means of the Ziegler Nichols, Tyreus Luyben and Haugen tuning technique. With these three tuning methods, the control parameters obtained were used for Proprotional-Integral (PI) and Proportional-Integral-Derivative (PID) control. Based on the study, the Haugen control shows the best results of the two other controls, namely with a rise time value of 11,361 ms, overshoot of 6,898%, and steady state at 1.3 s. This show that PI control using the Haugen tuning method able to control the motor well. Robustness tests have also been carried out because the steering system is operated in unpredictable environmental conditions. The control greatly influenced the performance and stability of EPS control in the car's steering system.

In the current age of globalization, the development of autopilots is superficial as the standard of living is improved through aerial surveillance, defense applications, and door- to-door transportation. To design the PID controller, a mathematical model is created to address the system identification for estimating longitudinal derivatives and to study the handling qualities of aircraft in order to improve piloting performance. This paper exhibits a comparative assessment between the classical closed-loop PID tuning methods like ZN, Modified ZN, Tyreus-luyben, Astrom- Hagglund and the modern control techniques like pole placement, LQR for the pitch controller design. The simulation results are displayed in the time-domain, which demonstrates the effectiveness of the approach used to design a robust controller.

HCl üretim endüstrisinde atık su arıtma işleminde kullanılan pH nötralizasyonu prosesi sürekli frekans salınım yöntemi kullanılarak parametreleri ayarlanmış bir kontrol edici ile set noktasında kontrol edilmiştir. PID kontrol edici parametreleri için iki farklı PID ayarlama tekniği Ziegler Nichols ve Tyreus Luyben uygulanmış ve performansları karşılaştırılmıştır. Kimyasal prosesin doğrusal olmaması ve kararsızlığı nedeniyle, ayar noktasına ulaşmak için minimum oturma süresi, azaltılmış salınımlar, kısa yükselme süresi, ofseti ortadan kaldırma, minimum yüzde aşma, yüksek stabilite gürültü sinyalleri ve yük etkileri varlığında optimum ve istenen kontrol performansı elde edilmesi hedeflenmiştir. Elde edilen deneysel sonuçlardan, Oransal İntegral Türev (PID) denetleyicisinin farklı ayarlama yöntemleri için zaman alanı özellikleri hesaplanmıştır. Tyreus Luyben ayar formülünün Ziegler Nichols yöntemine kıyasla daha az yükselme zamanı ve pik tepe aşım yüzdesine sahip olduğu ve daha küçük oturma zamanı verdiğini göstermiştir.

The temperature control and the composition control for the production process was used to evaluated a method to control the quality of methyl ester production in a reactive distillation column. The optimum condition at steady state was selected as the base case condition for the control study by using Aspen Dynamic Simulation. In this work, two controller settings for PID controller of each control loop were based on the Zeigler-Nichol and the Tyreus-Luyben tuning formulae. The controllability and performance of both control structures were compared. The result shows that the control loop using the Ziegler-Nichols setting gave better control performance than the other using the Tyreus-Luyben setting. It also found that the control structure based on temperature control gives the same control performance as the other based on composition control, but less expensive and less complicated to implement.

Ethylene is one of the most consumed products in the world, as it has many uses such as the production of nylon from its polymeric compound, the production of vinyl chloride, which is polymerized to polyvinyl chloride for the production of plastics, the production of ethylene oxide, used as a ripening agent for fruits, etc. The conventional method adopted in the production of ethylene is by steam cracking of naphtha at high temperatures. Naphtha is a hydrocarbon, so when cracked, it releases harmful carbon dioxide (CO2) into the atmosphere, and this brought about looking for alternative methods of producing ethylene. As discovered, ethylene can be produced by catalytic dehydration of ethanol, but the main limitation of this process is that the purity of ethylene produced by this approach may not be up to the desired polymer grade of 99.97%. As such, this work has been carried out to model, with the aid of Aspen Plus, and develop control techniques that would enable the process to meet up with the desired output maximum purity from the distillation column (100% ethylene at the top product of the distillation column). In line with that, P-only, PI, and PID controllers tuned with the Tyreus-Luyben technique, Zeiger-Nichols method, and a modified Tyreus-Luyben approach have been used for the control of this process. It was discovered that the PID controller tuned with the modified Tyreus-Luyben parameter had the lowest Integral Absolute Error (IAE) of 1.474 and Integral Time Absolute Error (ITAE) of 4.767 and, hence, it was found out that it could be adopted for proper control of this process, although limited to small upsets caused by disturbances in the system. It is, therefore, recommended that the PID control system developed should be applied on a physical set-up plant to study its real effect.

Water storage tank is important in many industries. A tank's water level must be kept at a particular desired level in order for the process to run as designed in manufacturing industry, efficient farming management in agriculture sector and many other reasons. An important issue of water level management in storage tanks is the control issue in closed-loop. The proportional integral derivative (PID) controllers are popularly applied for controlling liquid level. The limitation of PID controllers is that they are feedback-type controllers, where control action is only taken when the output is affected by error. However, conventional PID controllers are unable to effectively maintain liquid level, so the need for performance improvement in the current liquid level regulators is crucial. This research implement hybrid sliding mode controller with PID tuning gain scheduling (SMC-GSPID) controller to improves the robustness of the system. In addition, the conventional PID has been tested using three control methods of tuning which is Ziegler Nichols, Tyreus Luyben and Cohen Coon for comparison with the proposed method. All the results are validated using MatlabSimulink. The performance is evaluated using overshoot and steady state error for each controller. Based on the simulations, the suggested approach offers superior level position tracking performance with high precision compared to other PID control method with minimum overshoot of 2.9%, zero steady state error and shortest rise time which is 1.9 sec
