摘要 针对高阶加滞后对象稳定性分析的局限性,提出了预测PID控制器的设计方法,利用Kharitonov定理和边缘理论分析此系统在参数不确定情况下输入、输出的鲁棒稳定性,并给出了系统保持稳定的最大过程参数区间。仿真结果表明,当过程参数偏离标称值时,此类预测PID控制器的设计方法能够使系统保持很好的控制性能和鲁棒稳定性能。是一种值得在实际工程中推广应用的新型控制器。 A kind of Predictive PID controller for high order plus time delay process is put forward by using Kharitonov theorem and edge theorem.The analysis of robust stability with input and output when the parameters are uncertainty is analyzed.The largest ranges of process parameters to ensure stability of system are given.The simulation results show that performance and robust stability of the Predictive PID controller is suitable for practical application.
