中文摘要：
在实际应用中,非最小相位系统的负调会严重影响系统的平稳运行.本文利用简单易行且具有估计功能的预测PI控制来协调此类系统负调和调节时间相互制约的矛盾,针对不同工况的仿真实验表明该控制策略在保证调节时间基本一致的前提下,能够同时减小负调和超调,而且具有良好的鲁棒性能.
英文摘要：
In the practical application, the minus overshoot of non-minimum phase system will seriously impact the smooth operation. This paper uses simple predictive PI with estimating function to integrate the eontradiction between the minus overshoot and settling time. Simulation results of different working conditions show that the presented control strategy can decrease the minus overshoot and overshoot simultaneously ureter the premise of assuring the same settling time and has satisfactory robust performance.
