Stabilization of networked control system based on multiple communication channels with random delays

基于带有随机时滞的多通信通道,建立了离散时间网络控制系统模型.利用缓存对丢包进行补偿,并设计了状态反馈控制器,使系统达到随机稳定.采用锥型补偿线性化(CCL)算法得到了控制器增益的全局最优解.最后通过倒立摆系统的仿真例子验证了所提出方法的可行性.

The networked control system （NCS） is modeled in discrete-time domain over multiple communication channels with random delays. Buffer is used to compensate the dropouts of package and the state feedback controller is designed to make NCS stochastically stable. The cone complementarity linearization （CCL） algorithm is employed to compute the global optimal solvers of controller gains. Finally, A simulation for an inverted pendulum system shows the feasibility of the approach.
