具有线性状态观测器和参数补偿的交流矢量控制系统

AC. Vector Control System with Linear State Observer and Parametcr Compensation

本文提出了在交流矢量控制系统中设计线性状态观测器的新思路,并以此重构出负载扰动作前馈控制。为了克服电机参数变化对矢量控制准确性的影响,本文建议了一种新的参数变化补偿法。实验表明,系统加入了前馈控制和参数补偿后,动态性能得到了明显的改善。

A novel idea of designing and applying linear state observer is presented in this paper to reconstruct the load disturbance for feed forward control in AC. vector control systems. A new method of parameter compensation is also suggested to avoid the influence of rotor resistance variation on the accuracy of vector control. The experimental results show the dynamic performance of suggested system is apparently improved.
