极点

The design method of PID controller based on pole-assignment is proposed in this paper. The simulations indicate that this PID controlled inverter provides nice characteristics. A method of PI controller combined with instantaneous differential voltage is also proposed, which is equivalent to PID control in essence and can be seen as a simplified dual-loop form. Accordingly it is a simple but effective adjustment.

本文研究了基于极点配置的PID控制器的设计方法，仿真结果显示这种PID控制器性能优越，同时还提出一种PI调节器结合电压微分反馈的调节方式，并指出这种调节方式和PID调节其实是等效的，而且是一种简化的双环形式，因此是一种简单而有效的调节方式。

Secondly, in view of the identification problem after the change of MRAPC structure, the research has been extended to a kind of continuous system with time delay, and the robust convergence analysis for this model reference adaptive identification algorithm has been given. Using the intermediate value theorem in this analysis, the approximate problem in original analysis has been solved partly.
