Delta 域 H-infinity 控制器设计及其在高超声速飞行器纵向模型中的应用: 一种动态博弈方法

Abstract

In this paper, a game theoretic approach to develop H∞ control strategies for the Delta Operator System (DoS) is proposed. Two information patterns for the controller are considered and the conditions are presented in terms of iterative Riccati recursions. By using the delta operator, the calculation stiffness of the discrete system can be circumvented when the sampling frequency is extremely high. The proposed method is applied to the longitudinal flight control of the hypersonic flying vehicle and the effectiveness is verified by the experimental results.
