The study of microcomputer adaptive control system of controlled rectifier device

Conventional PID controllers perform poorly when applied to nonlinear system with delay and non-time-varying. A new kind of self-adjusting PID controller based on pole configuration and optimum long-term prediction is present in this paper. It was shown that this kind of controller has good real-time controlling static and dynamic performance when it is applied to rectifier device. It can automatically trace the variation of the load´s running condition and network structure. Also it has good anti-interference performance and robustness.
