摘　　要：针对电动机启动时冲击电流大、功率因数低、故障率高等问题,采用模糊控制与PID控制技术,设计了电动机启动控制系统。该控制算法不需要建立精确的数学模型,将该控制算法应用于电动机软启动控制系统表明:该控制器性能稳定可靠,对模型参数不依赖,具有较强鲁棒性。Directed at the characteristics of the greater impact of current, the lower power factor and the more likely faults when motors start. This paper highlights the technologies which consist of fuzzy control and PID control applied to motors starting control system. The application of the control algorithm which does not require the accurate mathematical models to motors soft starting control system shows more reliable controller performance, less dependence on the parameters of models, and stronger robustness.
