摘　　要：针对转差频率控制变频调速系统设计了模糊控制器,给出了模糊控制器的设计方法,包括具体的模糊集、模糊规则和模糊推理。仿真结果表明,该模糊控制器响应快、超调小、控制曲线平滑,其动态响应性能与稳态精度均优于PI控制器。This paper presents a mamdani-type fuzzy logic controller, which is applied to a VVVF system controlled with slip frequency. The guide to the design of the controller is presented, including detailed formulation of the fuzzy sets, the rule base and the fuzzy inference. Simulation results demonstrate that the fuzzy logic controller has quick response feature, small over reguating value and smooth control curve and moreover both dynamic response performance and steady-state control accuracy of the system are superior to traditional PI control.
