摘要
网络诱导时延是影响网络控制系统稳定性和动态性能的主要因素。针对一类仿射非线性被控对象模型,利用泰勒展开进行局部线性化。考虑网络诱导时延,采用状态反馈控制器,建立基于状态反馈控制器的闭环控制系统模型。通过Lya-punov方法证明,所得最大允许时延能够保证闭环网络控制系统稳定。最后以Simulink构建一个仿射非线性被控对象模型,通过仿真证明了本文方法的正确性和有效性。
Network-induced delay is a main factor that influences the stability and the dynamical performance of networked control systems. Aiming at a class of affine nonlinear system which can be linearized locally by Taylor method, the state feedback controller is introduced and the corresponding closed loop form of the networked control system is established. By Lyapunov method, it＇ proved that the maximum allowable delay bound obtained in this paper can ensure the system＇s stability. Finally, a affine nonlinear system is established by Simulink. The simulation results show the proposed method is feasible and effective.
