摘要
本文提出了一种新的简单而有效的异步电机控制方案。该方法将交流电机视为由电磁和机械两个子系统耦合起来的非线性系统,利用Lyapunov理论直接分析电磁子系统的稳定性,导出了一种使转子磁通和转矩跟踪给定值的电压控制律。本文还在该方法基础上发展了一种新的转速观测器,并给出了只需定子电流反馈的简化结果。实验证明了该方法的良好性能。
This paper presents a new control scheme for induction motor. This method applies the Lyapunov theory to analyze the stability of the electromagnetic subsystem and guarantees precise tracking of flux and torque. In addition,a speed observer and its simplified version are designed in this paper. The experiment verifies its good properties.
