延时网络控制系统的鲁棒L_(1)控制器设计

Robust L_(1) controller design for networked control systems with time delay

本文探讨了延时网络控制系统的鲁棒L_(1)控制器设计问题,针对给定的延时网络控制系统,建立了此系统的L_(1)(峰值-峰值)性能准则,且可以保证系统具有最劣情况下L_(1)性能约束且渐近稳定。在鲁棒L_(1)控制器中,通过锥补线性化(CCL)方法将其存在含有逆约束的LMIs形式转化为受其约束的最小化问题,这样可以运用MATLAB仿真对控制器的各参数进行求解,从而验证所提方法的可行性和有效性。

This paper discusses the design of robust L_(1) controller for time-delay networked control systems.For a given time-delay networked control system,the L_(1)(peak to peak)performance criterion of the system is established,which can ensure that the system has the worst-case L_(1) performance constraint and is asymptotically stable.In the robust L_(1) controller,the LMIs form with inverse constraints is transformed into the minimization problem constrained by it by the cone complement linearization(CCL)method.In this way,the parameters of the controller can be solved by MATLAB simulation,so as to verify the feasibility and effectiveness of the proposed method.
