Abstract: By using Lyapunov stability theory, an observer-based H∞ adaptive controller design method was proposed for a class of Hamiltonian systems with parametric uncertainties in this paper. First, the H∞ controller design problem was investigated for nominal Hamiltonian systems and the obtained result was extended to Hamiltonian systems with parametric uncertainties. The H∞ adaptive controller was also proposed. Next, considering the immeasurable of the system states and according to the structural characteristics of uncertain Hamilton systems, an observer-based H∞ adaptive controller design method was presented. Finally, the validity of the proposed method is verified by a numerical example.

摘要: 针对一类参数不确定Hamilton系统,根据Lyapunov稳定性理论,提出一种基于观测器的 自适应控制方法。首先,针对标称Hamilton系统,研究其控制器设计问题,将结果推广至含有参数不确定性的Hamilton系统,并给出其 自适应控制器设计方法。然后,考虑到系统状态的不可测性,根据不确定Hamilton系统的结构特点,提出一种基于状态观测器的 自适应控制器设计方法。最后,通过数值仿真验证所提方法的有效性。
