Full textENGLISH ABSTRACT: This thesis presents the design of a DSP based controller system for an auxiliary converter for generic energy storage connection to a line-interactive power compensator. The aim is to utilize a wide range of energy storage systems and incorporate them into the existing power compensator. This was done by adding a second converter to the system. The new controller was developed to control this converter and thereby the energy storage. A study was done on lead acid batteries, flow batteries and flywheels in order to gain a basic understanding of these systems and identify the requirements for their control. Based on these findings, a new DSP based controller and measuring system was developed. To test the new system a dc to dc converter was implemented for the control of lead acid and flow batteries. A dc to ac converter was also tested for the control of flywheel energy storage.

AbstractThis thesis aims to develop q controller for a aircraft starter/generatorusing a Digital Signal Processor (DSP)TMS320C25 Texas Instrument.A DSPvoltage regulator is prototyprd and verified in this work. A PWM inverteris emploted for driving the generator field. In addition to a convventionalscheme for PWM signal generator , we propose a new approach using the variable structure control( vsc).There are several factors, which can degrade the system performance .To cope with these factors, we use VSC for a presise voltage regulation. The switching nature of the PWM drive alsomakes VSC a reasonable choice for control law design . The experimental results shows that VSC has much betterperformance than a continuous PI controller. Robustness tests against rotatingspeed and loading current variable also give supportive results.

In this dissertation, the PD and PID control theory is used to design the digital controller and also take the digital signal processor (DSP) which has high-speed calculating ability as the major part for calculating. Then applied them to perform the positioning control system. First, we simulate the system response by computer, then applied the results from simulation to the real system. The structure design of the positioning control system is using the digital signal processing on the control board to go with the 8255 IC for the output of pulse wave to the servo motor driver. The AC servo motor drives ball screw and gets the position pulse signal of the system from the linear scale to feed back to the encoder interface of the control board. Then we can transmit the data back to the digital signal processor and also applies the control theory program that is loaded to the digital signal processor at the beginning to calculate the output of the next control command. During the operation stage, all signals are digitized, so it can say to be a full digitized control system. Finally, in this dissertation we base on the single axis positioning system for simulation and experiments also the two axes cartesian coordinate XY table for experiments.

In this thesis, the implementation of digital signal processor (DSP) on the multi-axis control application is investigated. Two major parts are included in the multi-axis control system; one is the interpolator which calculates the reference command for the trajectory planning, and the other is the servo controller that compensates the errors. The DSP possesses the capability of high-speed computation which is used to efficiently compute the complicated control algorithm. While collaborating with other peripherals, it practically connects to the real plant so that the design of the multi-axis interpolator and controller is completed.For verifying the DSP algorithm and the relative circuitry, the X-Y-Z table driven by the AC servomotor and the Stewart Platform based manipulator (SPBM) driven by the hydraulic systems are examined by computer simulation and experiment. The performance of the entire system is also tested and compared with the simulation results for both systems. Finally, the conceptualdesign of real-time multi-task function is proposed for the purpose of multi-axes synchronization.

Based on the digital signal controller dsPIC30F4011, which is generated by Microchip company, the thesis realizes servo motor position control. This implemented control is different from conventional programmable logic controller (PLC) servo motor control, which has the restriction that it needs human–machine interaction (HMI) and PLC sequence control, , axis control card and servo motor driver to work. Besides, every useable PLC module has to be from the same manufacturer. The proposed servo motor control can directly transfer the control instruction via HMI to digital signal controller. The digital signal controller can conduct servo position control program inside, and transfer sinusoidal pulse width modulation signals to drive six power switches of the three-phase inverter. The three-phase voltage will be generated from the inverter, and it can be used to control the servo motor. In other words, PLC and axis control card are replaced by a digital signal controller. As to simplify servo motor position control using digital signal controller, the thesis adopts vector control strategy with using direct and inverse Park transform, and direct and inverse Clarke transform to achieve d-q axis transformation so that servo motor can operate in the maximum torque during the whole process. The optical encoder of servo motor generates three feedback signals, ‘A’, ‘B’ and ‘Z’. The ‘Z’ signal is activated as an original point position signal of digital signal controller program, and is also used as the counter of servo motor rotate. The ‘A’ signal controls the counter register of counter motor inside of dsPIC30F4011 to achieve the precision position motor control. Meanwhile, by transforming the value in register to velocity feedback signal and calculating it with command velocity signal, we can realize close loop velocity control, which let the motor being able to rotate in steady speed. In this thesis, We use digital signal controller dsPIC30F4011 to realize servo motor position control system, and the system contains steady velocity control and precise position control toward the servo motor. Comparing to the conventional PLC position control system, the proposed method in thesis can highly decrease the cost and shrink the volume. Furthermore, the restriction of using the same brand devices no longer exist, which means we can perform servo motor position control according to the characteristic of the motors.

With the advance in technology, digital controllers are increasingly being used especia1ly in complex systems, including automobile electronic systems. Therefore, this thesis develops a DSP based design and implementation of an isolated inverter powered from a low dc source such as battery of vehicles. The main structure is consists of a push-pull converter and a single-phase full-bridge inverter. The front-stage push-pull converter boosts the lead-acid batteries voltage from 12V to 180V. The post-stage single-phase full-bridge inverter converts the 180V DC input voltage to an AC output voltage at 110 Vrms/60 Hz and then, the AC source can be used to supply the electrical loads at vehicles. This thesis introduces the operational principles of its push-pull converter and single-phase full-bridge inverter. The small signal models of both converters are also derived and the parameters of the PI controller are evaluated according to the specifications. To regulate the inverter output voltage, a digital signal controller dsPIC30F4011 is selected to implement the digital controller algorithms. A simple absolute value average method is used to feedback the inverter output voltage without delay time. By using the feedback control, the inverter output voltage is regulated under load and line variations. In addition, sinusoidal pulse-width-modulation (SPWM) with low switching losses unipolar voltage switching method is introduced in single-phase full-bridge inverter, to reduce the switching loss caused by the switches and improve the efficiency. Finally, a 100W digital inverter system is implemented to verify the functionalities of the proposed designs.

This thesis applies digital signal controller (DSC) dsPIC30F4011 to the speed control of three-phase induction motor. The speed control method of three-phase induction motor comprises vector control and scalar control. The former has better control performance. But it needs complicated mathematical model to implement the control strategies. Therefore, the scalar control has come into being another option for system designer in which the control system is not severely requested to be very stable. The digital control method has been widely used for induction motor at present. Based on DSC structure, this thesis applies V/f control, PID control, and Fuzzy control methods to the speed control of induction motor. The V/f control has the advantages of simple structure and easy implementation. In comparison with the other scalar control methods, the PID control has superior performances on parameters adjustment and control stability. The fuzzy control provides simpler control method than the other methods in which the system has highly non-linear characteristic or the differential equation can not be easily obtained. To verify the feasibility of the proposed method, this thesis employs one small induction motor (1/2 Hp) to fulfill the experiments. For assessing the control performance of the above methods, the step response and load variation experiments are studied based on different speed commands. Furthermore, this thesis also uses Visual Basic (VB) software to provide the personification of man-machine interface that the users can further monitor the operation state of induction motor.

In the past few years, the cars whose engines replaced by electric engines are gradually concerned, because of the shortage of petroleum. Brushless DC motors have high efficiency, high torque, high reaction speed, simple maintenance and easy control because they don’t have copper loss of rotor and having smaller moment of inertia. They are used in daily life and automatic production factory. The purpose of this paper is to use Digital Signal Processor (dsPIC33FJ256MC710) manufactured by Microchip Technology Inc to be a controller. And use modified Proportional- Integral Control to implement the speed control of a Brushless DC Motor. On a circumstance that grasp transfer function and parameters, using MATLAB-Simulink simulates the control of motors. The results of simulation are a basis of experiment. All the outcome from experiment are used to make response plot of speed. Finally, by means of comparison of response plot of traditional PI controllers I can make sure that the modified PI controllers are helpful to make it more stable and spend less time being a stable condition. At the meantime, the modified PI controllers can overcome the steady-state error more easily. And this make motors more precise and more stable in the speed control.
