时滞系统的多步预报控制

本文针对具有模型不确定性的时变大时滞系统，提出一种带监测及切换系统的多步预报控制算法。该方法的主要设计思想是对系统在包括时滞范围在内的未来时刻的输出作出预报，依此预报值进行滚动优化和闭环极点配置，同时，增加一层监测及切换系统，以保证整个系统的稳定性。理论分析及仿真实验表明，该方法能有效地用于时变大时滞对象的控制，是一种鲁棒性好的控制算法。

Long-range Predictive Control for System with Time Delay

In this paper, a Long-range predictive control algorithm with monitoting and changeover function is proPOsed to handle system with time-varying delay and model uncertainty. The main design idea is that the outputs of the plant, including the interval of the time delay, should be predicted and then based on the predictive outputs we make iterative option and pole assignment of the closed-loop system. The additional monitoring and changeover function guarantee the stability of the closed-loop system. The theoretical analysis and simulation show that this method can be used effectively for the control of system with time-varying delay and that this algorithm has a good robustness.
