摘要
模糊控制是当前控制领域研究的热点之一,在控制领域有着广泛的应用。本文根据电机转差频率控制的原理,结合模糊控制理论,设计了基于转差频率控制的变频控制系统的模糊控制器。详述了模糊控制的设计思想,包括具体的模糊化、模糊规则、模糊判决和清晰化过程。仿真结果表明,该模糊控制器响应快、超调小、控制曲线平滑的优点,完全满足系统可靠性、实时性的要求。
Fuzzy control technology is one of the important research and is widely used in the control system.A fuzzy logic controller using in the slip frequency control system of asynchronous motor is presented.The design of the controller is also put forward,including detailed formulation of the fuzzy sets,the rule base and the fuzzy verdict.The simulation results show that the fuzzy logic controller has quick response feature,small over regulating value and smooth control curve.It can meet the needs of real time control and stabilization for this control system.
