The aim of this work is to present a comprehensive computational analysis of the speed control of a permanent magnet direct current (PMDC) motor driven by a four-quadrant chopper for high-performance industrial applications. The paper provides a detailed mathematical modeling of the system, emphasizing the transient response characteristics and the motor dynamics under different operating conditions.
The design of the cascaded control architecture is thoroughly discussed, taking into account the physical limitations of the power converter. In addition, a systematic tuning procedure for the PI (Proportional–Integral) controllers of both the current and speed loops is presented. The pole-zero cancellation technique is employed to achieve effective loop decoupling while ensuring system stability and satisfactory dynamic performance.
Furthermore, advanced control strategies, including feedforward compensation of the back electromotive force (back-EMF) and an anti-windup mechanism to prevent integrator saturation, are incorporated into the control scheme. The computational results validate the effectiveness and robustness of the proposed system, demonstrating accurate reference tracking without overshoot, fast dynamic response, and excellent disturbance rejection capability under mechanical load variations.
