摘要
介绍了一种异步电动机的自适应控制,在Matlab/Simulink中对异步电动机控制系统的各个部分进行了仿真建模,完成了该控制系统的仿真。该方法用自适应方法将系统中某一信号作为虚拟控制信号,进而使系统简化,再应用李亚普诺夫稳定性理论实现该虚拟控制信号,达到控制要求。该设计方法的仿真结果表明,用该方法设计的异步电动机自适应控制系统能够获得较好的转速跟踪和磁链跟踪性能。
This paper presents an adaptive control method for induction motor .The simulation model of the induction motor＇s control system is set up on Matlab/Simulink .The strategy first treat certain signals in the system as fictitious control signals to get a simpler subsystem. An adaptive technique is used in this stage to design the fictitious controllers. Then the Lyapunov theory is applied to robustly realize the fictitious adaptive signals. The simulation result illustrates that thecontrol system of induction motor by adaptive sliding mode method can achieve better characteristic of the motor velocity and flux tracking.
