摘要
针对一类带有未知扰动的非线性切换系统,基于扰动观测器设计和有限时间鲁棒控制理论,研究抗干扰动态跟踪控制问题.首先,基于平均驻留时间(average dwell time,ADT)构造该系统所对应的切换信号,同时结合状态反馈信息和干扰估计信息设计一种PI型抗干扰复合控制器;其次,基于Lyapunov分析方法证明闭环系统的鲁棒性及有限时间的稳定性;最后,通过仿真算例验证了该算法的可行性.
For a class of nonlinear switching systems with unknown disturbances,based on disturbance observer design and finite-time robust control theory,the problem of anti-jamming dynamic tracking control is studied.Firstly,the corresponding switching signal of the system is constructed based on the average dwell time(ADT).Combining with the state feedback information and interference estimation information,a PI type anti-interference composite controller is designed.Secondly,the robustness and finite time stability of the closed-loop system are proven based on the Lyapunov analysis method.Finally,the feasibility of the algorithm is verified by a simulation example.
