摘　　要：针对传统的双反馈控制对于系统控制有超调过大,跟随误差较大等问题,提出了一种模糊自适应脉宽调制(Pulse Width Modulation,PWM)控制的双反馈控制算法。该算法通过模糊自适应控制器与PWM变换器相结合,对双反馈系统实现了高精度高鲁棒性的控制。仿真实验表明,模糊自适应PWM的双反馈控制算法系统可更好地抑制超调以及具有更小的跟随误差。In order to solve the problem that the system control overshoot and the follow error are too large in traditional double feedback control algorithm,a double feedback control algorithm of fuzzy adaptive PWM control was proposed.According to the algorithm,the fuzzy adaptive controller combined with PWM converter,the double feedback system realized the high precision control of high robustness.Simulation test showed that the fuzzy adaptive PWM double feedback control system could suppress overshoot and has small following error.
