中文摘要
      针对一类具有对象不确定和外部干扰的MIMO(多输入多输出)非线性系统提出了自适应鲁棒输出跟踪控制方案.使用了高斯径向基神经网络自适应补偿对象非线性,高增益观测器被用来估计不能直接测量的输出导数.此方法所设计的控制器不仅保证闭环系统稳定,而且所有状态有界以及跟踪误差一致终值有界.仿真结果充分表明了该方案的有效性和可行性.
英文摘要
      An adaptive robust output feedback control scheme is proposed for a class of multi-input multi-output nonlinear systems with plant uncertainties and external disturbances.The scheme employs a network of Gaussian radial basis functions to adaptively compensate for the plant nonlinearities.A high-gain observer is used to estimate the derivatives of outputs which can not be measured directly.Under mild assumptions,the closed-loop system is proven to be stable.The controller designed can guarantee that all the states in the closed-loop system are bounded and all the tracking errors are uniformly ultimately bounded .Simulation results demonstrate the effectiveness and feasibility of the proposed scheme.
