摘　　要：本文研究了一类线性时不变系统的双率采样控制问题。首先,考虑多个类型传感器系统的采样周期不同而引入双率采样方案;其次,通过以小采样周期重构状态信息来建立系统状态补偿机制,充分且实时利用不同时刻的采样信息,进而基于传感器采样时刻的信息设计切换控制器;最后,在Matlab/Simulink环境下通过仿真实验——智能车辆模型的轨迹跟踪仿真,证明了本文所提出的基于采样周期不同的切换控制方案的有效性。The H_∞ Control for a Class of Linear Time-variant Systems with Dual-rate Sampling is investigated in this paper. Firstly,considering the different sampling periods of different types of sensors,a dual-rate sampling scheme is introduced. Secondly,the state compensation mechanism is established by reconstructing the system state with a small sampling period,which make full use of the sampling information at different times,and a switching controller based on the sampling time is designed. Finally,the simulation of the trajectory tracking control by a Matlab/Simulink illustrates the rationality and effectiveness of the proposed switched control method based on multi-rate sampling.
