中文摘要
      针对具有严格反馈形式的随机非线性时滞大系统,设计了含有时滞项的随机控制Lyapunov函数,运用Backstepping技术,构造出一类输出反馈无记忆控制器.在此控制器作用下,所考虑的闭环系统实现概率意义上的时滞无关全局渐近稳定.并在无限时区优化指标函数的约束下,对控制器进行逆优再设计,以满足一定的性能要求.
英文摘要
       Recursive design scheme of decentralized output feedback global stabilization in probability was presented for a class of large-scale parameter strict-feedback nonlinear stochastic systems with time delay. A new form of stochastic control Lyapunov function with time delay was proposed to construct decentralized output feedback memoryless controllers which achieved global asymptotic stability in probability for the considered systems. The inverse optimal controllers are redesigned with cost functional includes penalty on control effort, and when it has an infinite gain margin.
