2-degree-of-freedom deadbeat control with disturbance compensation for PMSM drive system using FPGA

In recent years, permanent magnet synchronous motor is widely used due to its high efficiency and maintenance free features in the industry. high accuracy position control and speed control performance in the servo system is required, so the high response performance in the current control system is required. In this paper, the moter drive system applying the 2-degree-of-freedom deadbeat control with disturbance compensation method is propsed to realize high tracking accuracy and robustness to the system parameters variations. The advantages of the proposed method was compared with the conventional deadbeat control method through simulations and experiments.
