研究广义 Hamilton 系统的观测器设计和应用问题.首先,根据广义 Hamil-ton 系统的结构特性,提出一种新的观测器设计方法: 扩张+反馈法. 基于该方法,文中设计了两种观测器, 一种是针对系统结构中不含参数摄动的情况而设计的; 另一种是自适应观测器,则是针对系统结构中含参数摄动的情况而提出的. 然后,运用所得到的观测器研究广义 Hamilton 系统的基于观测器的 H∞控制设计问题,给出一种新的设计方法. 最后,把得到的结果应用于电力系统,给出单机无穷大系统的状态观测器和基于观测器的 H∞ 控制方案.仿真结果表明,所提出的方法是非常有效的.
In this paper, we study the design and application of observers for generalized Hamiltonian systems.First, according to the structural characteristics of the generalized Hamiltonian system, we propose a new observer design method: dilation + feedback method.Based on this method, we design two kinds of observers , One is designed for the system structure without parameter perturbation; the other is the adaptive observer, it is for the system structure containing the parameter perturbation of the situation proposed.Then, using the resulting The observer is used to study the observer-based H∞control design problem of a generalized Hamiltonian system, and a new design method is given.Finally, the results are applied to the power system, and the state observer and observer based observer H∞ control scheme.The simulation results show that the proposed method is very effective.
