Aiming at the problem caused by the PI integral saturation of speed regulator in permanent magnet synchronous servo system, a novel anti-windup (AW) design which is based on the mind of back-calculation was presented. The proposed AW design provided a tuning principle for the back-calculation gain, which is determined according to the input and output status of PI regulators. The new method of AW was compared with the classical AW by simulation and experiment. The simulated and experimental results demonstrate the feasibility and advantage of the new AW design. The PI regulator with the proposed AW design can reduce the overshoot of system dynamic response with the similar response speed, and improve the dynamic behavior especially in wide range of dynamic variation.
