| 摘 要： | 本文讨论了双非线性系统的状态观测器构成问题。当感应电动机采用变频调速时,描述调速系统的特性方程是双非线性微分方程。本文提出用非线性磁通观测器构成感应电动机的调速系统,实验结果证明,这个观测器能观测感应电动机的磁通,使得电动机的磁通保持恒定。由实验结果表明,这种系统具有良好的调速性能。

| Abstract: | A class of nonlinear systems which are binonlinear is studied.A nonlinearobserver is offered in these systems.In particular,it is a typical binonlinear model in that when variable frequencyis adopted to control the speed of the induction motor by means of nonlinearobservers,the flux-linkages of motor can be reconstructed.Thus,the method ofspeed control,based on observable flux-linkage,is obtained for the induction motor.Simulation and experimental results show that this method is practical.The purpose to follow up is how to carry out both a theoretical and anexperimental study of possible practical realization of the A.C.motor drive. |
