带有自校正的PID预测计算机控制算法研究

常规PID控制有许多不完善之处，其中最主要的问题就是PID控制器参数一旦调整好后。在整个控制过程中都是固定不变的，从而使系统很难达到最佳的控制效果。提出了一种带有自校正的PID预测计算机控制算法，包括控制结构、控制器设计以及变换为具有PID结构形式的过程。仿真结果表明带有白校正的PID预测控制算法调整时间短，平滑性较好，表明该带有自校正的PID预测计算机控制算法的有效性和较好的控制综合性能。

An Algorithm of PID Predictive Computer Control with Self-adaptive

The common PID control has many defects, the leading problem is that the PID controller parameters adjusted are unchanged in the whole control course. So the system does not come up to the best control result. This paper introduces an algorithm of PID predictive computer control with self - adaptive, including control structure,the device of controller, and the course of transformming into PID structure. The emulation result expresses that the algorithm of PID predictive computer control with self - adaptive has short adjust time and better slippery. It also shows that the algorithm of PID predictive computer control with self - adaptive is effect tive and has better synthetic control capability.
