一类不确定非线性系统的有限时间输出调节方法
针对一类外系统是中性稳定的不确定非线性系统的输出调节问题,提出一种有限时间收敛的输出调节器的设计方法。该方法结合内模原理和有限时间稳定性理论,先根据输出调节问题可解的必要条件,将原受控系统和外系统的输出调节问题转化为增广系统的镇定问题;再利用动态面技术设计一种鲁棒有限时间稳定的镇定器,从而保证闭环系统的信号是全局最终有界的,并且使调节误差在有限的时间内收敛至任意给定的范围内。仿真结果说明了所设计调节器的有效性和可行性。...

| Abstract_FL | To solve an output regulation problem of a class of uncertain nonlinear systems driven by a line-ar neutrally stable exosystem, a finite-time convergent output regulator design method is proposed. Ac-cording to the design,the internal model principle was combined with finite-time stability theorem. First-ly,based on necessary conditions of output regulation problem,the output regulation problem of the given plant and exosystem was transferred to a robust stabilization problem for the so-called augmented system. Secondly,a robust finite-time stable controller was designed by using the dynamic surface technique, which guaranteed all the closed-loop signals to be bounded and regulation errors to converge to an any given range in finite time. Simulation results show that the proposed regulator is effective and feasible. |
