根据输出反馈可以等价于状态反馈，利用并矢分解对一类多变量系统提出了一种并矢型动态补偿器，它的设计可以综合状态空间法和频域法两种优点，仿真效果明显，便于在工程技术中应用。 According to the output feedback, it can be equivalent to the state feedback. By using the parallel decomposition, a parallel vector dynamic compensator is proposed for a class of multivariable systems. Its design can combine two advantages of the state space method and the frequency domain method. The simulation results are obvious , Easy to apply in engineering technology.
