摘　　要：针对具有未知非线性函数和不确定外部扰动的随机大系统,设计分散预设固定时间有界H_(∞)控制器.该文控制器能使大系统中各子系统的跟踪误差被预设有限时间性能函数约束,使各子系统的输出较好地跟踪参考信号,确保各子系统的所有信号均依概率固定时间有界稳定.该文控制器具有可行性.The decentralized prescribed fixed-time bounded-H_(∞)controller was designed for large-scale stochastic systems with unknown nonlinear functions and uncertain external disturbances.The tracking error of each subsystem in the large-scale system could be constrained by a prescribed finite-time performance function,so that the output of each subsystem could track the reference signal well.At the same time,it could ensure that all the signals of each subsystem were fixed-time bounded stable in probability.The controller was feasible.
