摘　　要：针对时滞分布参数系统,设计中和控制器。考虑该控制器作用过程中各控制点的控制过程可能存在非连续性的问题,将中和控制方法与非周期间歇控制方案结合,研究系统稳定性。利用Lyapunov稳定性理论并结合LMI处理方法,得出时滞分布式参数系统间歇非周期中和控制器存在的充分条件。最后结合所给条件,给出一个数值仿真说明其有效性。For distributed parameter systems with delay,the neutralization controller is designed.Considering the discontinuity of the controller in the process of operation,the stability of the system is studied by combining the neutralization control method with the aperiodically intermittent control scheme.By the Lyapunov stability theory and the linear matrix inequality,a sufficient condition is obtained for the stable aperiodically intermittent neutralization controller to exist in the distributed parameter systems.Finally,combined with the given conditions,a numerical simulation is conducted to illustrate the effectiveness of the controller.
