本文研究的是混合H<inf>2</inf>/H<inf>∞</inf>控制问题。本文的目的是给出一种迭代算法,用于寻找混合 H<inf>2</inf>/H<inf>∞</inf> 控制问题的次优静态反馈控制器。我们算法的关键思想是构造两个“控制器集”:一个是一组改进给定控制器的闭环映射的 H<inf>2</inf> 范数的控制器,另一个是一组其元素满足 H<inf>∞</inf> 范数约束的控制器。使用两个控制器集,我们提出了一种迭代算法。如果满足 H<inf>∞</inf> 范数约束直到目标闭环图的 H<inf>2</inf> 范数收敛到 H<inf>2</inf> 最优值,则所获得的控制器要么是全局最优解,要么是 H<inf>∞</inf> 范数约束边界上的次优解。
This paper is concerned with the mixed H<inf>2</inf>/H<inf>∞</inf> control problem. The purpose of this paper is to give an iterative algorithm for finding a sub-optimal static state feedback controller for the mixed H<inf>2</inf>/H<inf>∞</inf> control problem. The key idea of our algorithm is to construct two “controller sets”: one is a set of controllers that improve the H<inf>2</inf> norm of the closed loop map for a given controller and the other is a set of controllers whose elements satisfy the H<inf>∞</inf> norm constraint. Using two controller sets, we propose an iterative algorithm. The obtained controller is either the global optimal solution if the H<inf>∞</inf> norm constraint is satisfied until the H<inf>2</inf> norm of the objective closed loop map converges to the H<inf>2</inf> optimal value or a sub-optimal solution on the boundary of the H<inf>∞</inf> norm constraint.
