针对一类上三角随机非线性系统的输出反馈控制问题,首先利用反推技术,为其对应的标称系统设计稳定的输出反馈控制器;然后利用低增益齐次占优技术,为整个系统设计输出反馈控制器.所设计的控制器能保证闭环系统的平衡点为依概率全局渐近稳定的,并将低增益齐次占优技术推广到了随机系统,首次解决了一类上三角随机系统的镇定问题.最后通过数值仿真验证了所提出控制方案的有效性. In order to solve the output feedback control problem of a class of upper triangular stochastic nonlinear systems, a stable output feedback controller is designed for the corresponding nominal system by using the backstepping technique first. Then, by using the low gain and homogeneous dominance technique, the entire system design Output feedback controller.The designed controller can guarantee the equilibrium point of the closed-loop system as global asymptotic stability in probability and extend the low-gain homogeneous dominant technique to the stochastic system, for the first time solve the problem of a kind of upper triangular random system Finally, the effectiveness of the proposed control scheme is verified by numerical simulation.
