An output feedback regulation problem is considered for a class of high‐order feedforward nonlinear systems with delay in the input under measurement sensitivity. The key features are that the considered systems have uncertain high‐order feedforward nonlinearity and unknown time‐varying delay in the input. Then, the controller is supposed to be engaged where the output feedback information is distorted by measurement sensitivity. Our proposed controller has two gains—fixed and adaptive gains. The fixed gain is first designed to compensate for measurement sensitivity, and the adaptive gain is next utilized to dominate both unknown input delay and uncertain high‐order feedforward nonlinearity. Simulation examples are given to highlight the advantage of our control scheme.

测量灵敏度下输入未知时变延迟的一类高阶前馈非线性系统的输出反馈调节

对于一类高阶前馈非线性系统，考虑其输入在测量灵敏度下的延迟，存在输出反馈调节问题。关键特征在于，所考虑的系统具有不确定的高阶前馈非线性和未知的输入时变延迟。然后，假定控制器参与其中输出反馈信息因测量灵敏度而失真的情况。我们提出的控制器具有两个增益-固定增益和自适应增益。首先设计固定增益以补偿测量灵敏度，然后利用自适应增益来控制未知的输入延迟和不确定的高阶前馈非线性。仿真例子说明了我们控制方案的优势。
