摘要
在用广义模型描述被控过程的基础上,本文提出一个极点配置最优预报自校正PID控制算法,该算法兼有PID和自校正,以及克服时滞的最优预报器的特点。计算机数字仿真结果表明这种控制策略对具有未知或时变分数时滞系统是非常有效的。
Simultaneous estimation of process parameters and process time delay can be achieved by applying a general model. Based on this model ,an algorithm of the pole assignment optimal prediction self-tuning PID contrller which adapts to the process with unknow or time-varying fractional delay is proposed in this paper. The algorithm has not only PID control features, but also self-tuning control and optimal prediction features that may overcome the time delay. Simulation results indicate that the general model algorithm are very effective in on-line identification and control for time-varying fractional delay systems.
