研究了单输入单输出非线性不确定系统的鲁棒输出跟踪控制。在标称系统可输入／输出线性化、不确定性项有界且满足广义匹配条件的情况下，可得到系统的高增益鲁棒输出跟踪控制器。鲁棒控制器仅依赖于设计参数和不确定性的界。将该方法应用于飞机纵向高阶非线性动态的控制器设计，并进行了数字仿真。结果表明了该方法的有效性。 The robust output tracking control of a single input single output nonlinear uncertain system is studied. Under the condition that the nominal system can be input / output linearized, the term of uncertainties is bounded and the generalized matching conditions are satisfied, a high-gain robust output tracking controller of the system can be obtained. Robust controllers rely only on the boundaries of design parameters and uncertainty. The method is applied to the design of high-order non-linear dynamic controller of aircraft and the digital simulation is carried out. The results show the effectiveness of this method.
