Being high efficiency, high power, low inertia, high steady state starting torque and comparatively simple control methods PMSMs find many applications in traction systems and electric vehicles (EVs). This is the main reason why control strategy research of synchronous motor has attracted a lot of attention. With advancement in power electronics technology and tremendous research over the years on motor control theory, speed control systems of synchronous motor are widely used. Vector Field oriented speed controller that regulates the speed of a PMSM based on Park and Clarke (D-Q transformation) is most famous and widely used to control the speed of various electrical motor drive systems. In this method, a quadrature axis current component developed using speed control provides field oriented vector control. In this project, 400 V four poles, three phase PMSM test bench is simulated using two current controlling techniques – Current Hysteresis Control and Pulse Width Modulation (PWM) control. Based on mathematical equations of PMSM, the dynamic model is designed along with closed loop speed control using traditional proportional-integral-derivative (PID) controller. Also following theory and mathematical equations on Park and Clarke Transformation abc to dq and dq to abc blocks are designed in Simulink. In addition to that, Pulse width modulation (PWM) block and three phase voltage source inverters (VSI) block is designed using Simulink library. As mentioned above simulation using Mathwork’s MATLAB/Simulink package illustrates d-q transformation control of PMSM drive systems using both techniques. Performance of both these techniques is presented along with graphical analysis.
