网络控制系统的主动变采样控制器设计(英文)

Controller Design for Networked Control Systems with Active Varying Sampling Period

利用主动变采样周期方法,研究了具有网络诱导时滞和数据包丢失的网络控制系统的H∞控制器设计问题,其采样周期在一个有限集内切换。新提出的主动变采样周期方法能够保证网络带宽的充分利用。在为具有主动变采样周期的网络控制系统设计H∞控制器时,使用了基于线性矩阵不等式的多目标优化方法和基于参数不确定性的方法。仿真结果说明了所提出的H∞控制器设计的有效性。

The problem of designing H∞ controllers for networked control systems with both network- induced time delay and packet dropout was studied by using active varying sampling period method, where the sampling period switched in a finite set. The newly proposed active varying sampling period method could ensure the sufficient use of network bandwidth. A multi-objective optimization methodology in terms of LMIs was proposed to deal,with the problem of H∞ controller design for NCSs with active varying sampling period, and the parameter uncertainty-based method was adopted for H∞ controller design. The simulation results illustrate the effectiveness of the proposed H∞ controller design.
