A Control-Based Model of IPMSM with Hysteresis Current Control PWM

This paper presents an electric circuit model of an IPMSM which is based on the 90-degree torque angle vector control method. The electrical and mechanical characteristic equations of an IPMSM are modeled with one electric circuit. The model is simple yet accurate. It is tested for speed control with the hysteresis current control pulse width modulation (HCC PWM) technique. This method of controlling the current is one of the most popular methods due to its simplicity and ease of implementation. The HCC PWM is well explained in this paper using op-amps and SR flip flops. The motor model and its control are simulated in Power Simulation environment and show good and fast performance in tracking the commanded speed and load torque.
