摘要
针对工业控制中较常见的单容纯时滞系统难于控制的问题,考虑优化控制对象的鲁棒性强和阶跃响应时间短等综合性能,依据纯时滞系统的两次优化控制方法,利用误差绝对值与时间的积分(ITAE)作为性能评价标准,提出一种纯时滞系统鲁棒控制优化的设计方法,设计方案包括分时模型的选择和参数优化两部分.给出了相应的优化算法,使用克隆和混沌技术进行参数优化.最后给出优化参数的系统阶跃响应的对比结果,仿真结果验证了本文时滞系统的控制优化设计方法有效准确.
The existed trouble is that the one capacitor system with time-delay are difficult to control usually in industrial control field.The aim of optimal control for a pure time-delay system is to form a robust-control system with short step response time based on the method of twice optimum control（TOC）.The optimal robust control method of a pure time-delay system is presented under the evaluation standard of integral time and absolute value of error（ITAE）.This method involves two stages,i.e.time-dividing model choice and parameters optimizing.The corresponding optimal algorithm is given.The clone and chaos technology is used to optimize parameter.At last,the comparison results of system response for optimal parameter is given.The experimental results show that this optimal control method is efficient and accurate.
