Abstract:

An online parameter estimation methodology using the d-axis current injection, which can estimate the distorted voltage of the current-controlled voltage source inverter (CCVSI), the varying dq-axis inductances, and the rotor flux, is proposed in this study for interior permanent magnet synchronous motor (IPMSM) drives in the constant torque region. First, a d-axis current injection-based parameter estimation methodology considering the nonlinearity of a CCVSI is proposed. Then, during current injection, a simple linear model is developed to model the cross- and self-saturation of the dq-axis

Abstract:

A closed-loop auto-tuner proportional integral derivative (PID) controller for tuning the DC-link voltage, voltage neutral controllers, and DQ axis current for a power factor corrector with Vienna rectifier is developed and discussed in this study. In traditional tuning of these control loops, it is needed to tune one loop at a time manually, which tends to be a difficult and time-consuming process. In this work, we add a closed-loop PID auto-tuner in the control design will help to simplify and speed up this process by tuning all the 4 PID controllers in a single simulation running in a close

Abstract:

The coordinate transformation method of asymmetric dual three phase synchronous motor (ADTP-SM) is a Double dq transform using two dq-axes and a vector space decomposition (VSD) model method using the orthogonality of ADTP-SM. There are several studies comparing the two methods in a healthy state, but few in a single-phase open fault state. In the healthy, when the VSD model is applied, different harmonic orders of the phase current are projected onto the dq and xy-axes (the axis for controlling harmonics of the phase current), and the two-axes are orthogonal, so it can be controlled stably.

Abstract:

A smooth coupling is implemented between the grid and doubly fed induction generator-based wind turbines (DFIG-WTs) during grid voltage imbalance. The nonlinear characteristics of a grid-connected DFIG-WT system may increase stresses on the mechanical and electrical components of wind turbines. Such difficulties are greatly increased during periods of voltage imbalance. Consequently, in this paper, a new control scheme is proposed to regulate DFIGs in order to support a smooth connection to the grid during voltage imbalance. In synchronization mode, the positive sequence of the rotor dq-axes c

Abstract:

This paper presents a cascade predictive control structure based on field-oriented control (FOC) in the dq rotor reference frame for the synchronous reluctance machine (SynRM). The constant d-axis current control strategy was used, and thus, the electromagnetic torque was directly controlled by the q-axis current. Because the model of the two axes of currents from the inner loop is a coupled non-linear multivariable one, to control in a non-interaction and linear way the two currents, their decoupling was achieved through feedforward components. Following the decoupling, two independent monova

Abstract:

Field-oriented control (FOC) has achieved great success in permanent magnet synchronous motor (PMSM) control. For the PMSM drive, FOC allows the motor torque and flux to be controlled separately, which means the torque and flux are decoupled from each other. Since the torque control is achieved by the speed controller, it can be considered that the speed and the flux of the PMSM are also decoupled from each other and can be controlled separately. In this paper, we propose a PMSM vector control using decoupled speed and flux controllers based on the proportional-resonant (PR) control method. A

This paper presents a performance enhancement of a permanent magnet synchronous generator (PMSG) system with control of generator-side converter for a wind turbine application. This method uses zero d- axis stator current control to minimize winding losses of the generator. The electromagnetic torque of the generator is correlated with the magnitude of the qaxis stator current, while the daxis stator current is regulated at zero, the control scheme decouples the dq-axis stator current control through a vector con- trol for the generator-side converter.

Abstract:

Modeling, design, fabrication, and testing of single magnet, single axis DC attraction type levitation system (DCALS) has been presented in this chapter. The proposed two loop scheme is more attractive from control point of view than the mostly reported single loop position control. The order of the levitated system (plant) has been reduced by one due to the use of a controlled current source as the excitation of the magnet-coil. The analysis and design of the position controller becomes easier after considering the reduced order plant transfer function. The controllers have been designed based on classical control theory utilizing root-locus and frequency domain technique. The realization of the controller also becomes simple due to the use of analog circuits.

Abstract:

This chapter presents a simple method to efficiently predict the rotor speed for a sensorless vector control technique applied to induction motors (IMs). The motor is supplied by a Simplified Split-Source Inverter (S3I), which provides dc-boosting and ac-inversion processes during input voltage sag. It also has a wider modulation range and a lower harmonic content than conventional boosting inverters. With this contribution, it is possible to efficiently estimate the rotor position directly without needing a PI controller with fluctuated supply voltage. The proposed strategy can be divided into three parts. The first uses a dual-loop controller to obtain the reference DC-boosted voltage of the SSI and regulate the input current. The second is the suggested observer for speed detection, which is derived from the principles of phase axis relations of the adopted machine currents and the indirect rotor flux orientation control (IRFOC) approach. With a newly developed space vector modulation, the third part will generate the switching pulses of the inverter switches. A complete analysis has been conducted to ensure the observability of the proposed technique. A series of PLECS simulations were conducted to verify the concept. The obtained results validate the proposed strategy with the S3I topology.

Abstract:

In order to enhance the control stability and anti-interference ability of quadcopter, this paper presents a quadcopter based on double-layer PID control, and designs a quadcopter with STM32 as the main controller, and simulates and verifies its control system attitude. Firstly, the nonlinear attitude mathematical model of the aircraft is established by the four-element method, and the relationship between the attitude angle and the angular velocity of the aircraft is obtained by solving, so that the measurement data of multi-attitude sensors of the four-axis aircraft can be better fused. Then, according to the deviation between the target attitude and the current attitude of the aircraft, a double-layer PID control method is proposed based on the traditional PID controller. The outer loop controls the angle of the aircraft and the inner loop controls its angular velocity to improve the adaptability and accuracy of the aircraft. At last, the attitude of quadcopter with two controllers is simulated and compared by Matlab simulation software. The simulation results show that the quadcopter with PID control has a slow response time, and the attitude stabilization time is 2.7s, while the quadcopter with double PID control has a fast response time, and the attitude stabilization time is 0.4 s, which has good control stability and strong anti-interference ability, and improves the adaptive ability and robustness of aircraft control.
