无速度传感器交流调速系统由于速度估算滞后，在突加负载时动态降落很大，无法满足性能要求。利用模糊控制和PI控制器构成模糊PI复合速度调节器，仿真结果表明系统性能得到了明显的改善。
Speed sensorless AC speed regulation system due to the lag of speed estimation, sudden drop in the dynamic landing a lot, can not meet the performance requirements. The fuzzy PI composite speed regulator is composed of fuzzy control and PI controller. The simulation results show that the system performance has been significantly improved.
