摘要
本文通过引入Razumikhin方法解决具有时变时滞的随机非线性系统的输出反馈依概率全局渐近稳定问题。基于Razumikhin方法和反推设计技术,构造合适的观测器和Lyapunov函数,从而使闭环系统依概率全局渐近稳定。通过本文设计的控制方案,彻底消除了传统结果对时滞导数的限制。最后的仿真实例证明了该方法的有效性。
In this paper,Razumikhin method was introduced to solve the output feedback stability problem of stochastic nonlinear systems with time-varying delay.Based on Razumikhin method and Backstepping design technique,an appropriate observer and Lyapunov functions were constructed while eliminating the derivative limitation of time delay,so as to stabilize the output feedback of the closed-loop system.By using the control scheme designed in this paper,the limitation that the derivative of time delay in the traditional results was completely eliminated.Finally,the simulation results showed the effectiveness of the method.
