摘　　要：针对含有数据丢失的不确定性连续系统,采用切换控制理论对其进行研究.首先,讨论含有损失数据连续系统的工作状态和相应的模型;然后,采用间歇式控制方式,即在数据持续反馈期间对系统持续施加控制信号,在数据持续丢失期间不施加控制信号,对含有最大数据丢失率和外部干扰的不确定性系统,利用切换控制原理对其进行研究,并以定理形式给出控制器设计方法;最后,通过仿真实例表明所提出方法的有效性.The uncertain continuous system with data loss is studied by using the switching control theories. Firstly, the working cases and the corresponding model of the continuous system with loss data are discussed. Then, the intermittent control is employed, namely during data continuous feedback, a control signal is applied to the system, and during the data continuously losing, the control signal is not exerted to the system. The uncertain control system with maximum data loss rate and external disturbance is studied by using the principle of switching control, and the controller design method is given in the form of the theorem. Finally, a simulation example is given to illustrate the effectiveness of the proposed method.
