Anti-windup speed regulator based on model predictive control

An anti-windup designs methodology using model predictive control (MPC) of a permanent magnet synchronous motor (PMSM) speed regulators is proposed. The performance of PMSM servo system is limited by inverter output current constraints, the integral windup phenomenon can results in overshoot of system dynamic response and increase system regulation time, which is derive from traditional proportional-integral (PI) speed regulator in big step response process. This paper utilize MPC algorithms application to the speed regulator, the validity of the applied speed regulator was tested respectively via simulation and experiment, excellent results were obtained with respect to the speed trajectory tracking, stability, and disturbance rejection especially when encounter a wide range of speed variation.
