距离度量下的一类非线性系统输出反馈控制

Output Feedback Control for a Class of Nonlinear Systems in Gap Metric

针对一类非线性项下三角形依赖的输出反馈控制系统,在非线性距离度量框架下,设计状态观测器和反馈控制律稳定闭环,并分析控制器的鲁棒性.在有测量误差和输入误差时,控制器实现了闭环在距离度量意义下的稳定.当模型扰动小于正常数时,控制器可实现对于模型扰动的鲁棒稳定性.

For the lower triangular nonlinear system,an observer and feedback control system are constructed to stabilize the closed-loop within the framework of nonlinear gap metric.In the presence of input error and measurement error,the designed controller is able to stabilize the closed-loop in the sense of gap metric.In the case that the plant perturbation is smaller than some positive constant,the controller achieves robust stability to the plant perturbation.
