摘要
针对感应电动机调速控制系统,研究了基于非线性状态反馈控制和Lyapunov积分控制的两种控制方法,两种控制方法均可实现感应电动机转速和磁链的完全动态线性解耦控制,但后者增加了积分控制及电流控制环节,使系统响应增强.仿真结果表明,他们均具有良好的调速控制性能.通过对两种方法的比较和分析,两种控制方法具有良好的稳态特性,但后者的动态特性更好,且对电阻参数的变化其鲁棒性更强.
In this paper a comparison study is made of two nonlinear control techniques for induction motors, namely nonlinear state feedback control and Lyapunov integral control. With thin two control methods the completely dynamic decoupiing and linear control is realized. The addition of the integral term and current control the latter improves the dynamical properties of the system. The simulation results show that these have satisfying performances. The latter has better dynamical properties and the high robustness of the motor parameters uncertainty.
