摘要
面对当前使用的平均驻留时间的反馈控制方法、基于切换原理的反馈控制方法受到外界环境干扰,导致控制效果不佳的问题,提出干扰输入影响下离散线性切换系统的反馈控制方法。分析离散线性切换系统,设定切换信号是唯一的和任意的2种情况,由此设计线性切换状态下的反馈控制器,在干扰输入影响下,构建被控对象模型,描述输出反馈问题,简化信号非统一输入过程,确定任意切换时间内存在的2个控制量,设计降阶控制律,构造一阶输出反馈律,实现有限时间镇定反馈控制。实验结果表明,该方法输出的响应曲线与实际最大时延上界为6 ms的控制情况一致,说明反馈控制效果较好。
Facing the problem that the average dwell time feedback control method and the feedback control method based on switching principle are disturbed by the external environment,resulting in poor control effect,a feedback control method for discrete linear switched systems under the influence of interference input is proposed.The discrete linear switching system is analyzed,and the switching signal is set to be unique and arbitrary,so the feedback controller in the linear switching state is designed.Under the influence of interference input,the controlled object model is constructed,the output feedback problem is described,the signal nonuniform input process is simplified,the two control quantities existing in any switching time are determined,and the reduced order control law is designed,A firstorder output feedback law is constructed to realize finite time stabilization feedback control.The experimental results show that the output response curve of this method is consistent with the control situation with the upper bound of the actual maximum time delay of 6 ms,indicating that the feedback control effect is good.
