Speed and current feedback loops control for permanent magnet synchronous motor using PID controller

The major contribution of this paper is shows how to control the speed of Permanent Magnet Synchronous Motor (PMSM) by using Proportional Integral and Derivative (PID) controller. In this work, proposed PID controller is used in both speed and current feedback loops to control the speed and torque respectively. The proposed PID controller having the advantages which are less oscillatory response, less overshoots and takes less settling time for the speed response compared with existing PID controller used in speed control loop. The PMSM drive is used in electric vehicle, electric traction, robotics and industrial dive applications. The PMSM having the salient features which are high efficiency, high torque density, low torque ripple, high power density and robust construction compare to dc, induction, Switched Reluctance Motor (SRM) and Brush Less Direct Current (BLDC) motors. In this paper, the proposed PID controller is developed based on Field Oriented Control (FOC) strategy is well used to achieve the good speed response of PMSM drive using MATLAB R2019b/Simulink software. The proposed PID controller provides an excellent steady state and dynamic speed response in terms of rise time, peak time, settling time and overshoots. In addition, proposed PID controller has overcome the drawbacks of Proportional (P) and Proportional Integral (PI) controllers. The P and PI controllers which process only first order unstable systems can be stabilized and higher order processes cannot be stabilized respectively. These controllers compromised if the system dynamics change over time.
