| 摘 要： | 在异步电动机磁场定向数学模型的基础上,给出了恒磁条件下异步电动机的解耦模型及传动系统的线性状态方程,并提出了重构负载扰动转矩的线性状态观测器。利用重构的负载转矩在矢量控制系统中进行扰动前馈,明显地提高了系统的抗负载扰动能力,从而为进一步提高矢量控制系统的动态性能开辟了一条有效的途径。

| Abstract: | This paper presents the application of linear state observer to loaddisturbance reconstruction in AC. vector control systems. The decoupled modeand system linear state eguation of the asynchronous motor are obtained under theconstant field condition based on field-oriented mathematical model. The distur-bance forward-compensation is taken to improve apparently the system anti-dis-turbance ability. Therefose, it gives an effective way to improve the dynamic per-formances of AC. vector control systems. |
