摘要
本文证明了对任意可实现的控制对象p,都存在内稳定p的物理可实现的控制器。并且,l^1优化设计问题的可行域限制在可实现的控制器集合上后,性能指标的下确界不变。对物理不可实现的l^1最优控制器给出了使之成为可实现的,同时又不明显降低最优性能指标的修正方法。方法简单清晰,并给出了算例。
In this paper, we have proved that for anly realizable plant p there exist controllers which stabilize p and are realizable, and the infimum of index for l1 optimization problem restricted to realizable controllers is equal to the one with no restriction. A method for modifying unrealizable l1 optimal controller to realizable one is given. The modified controller can arbitrarily approach the infimum of the index. This method is simple and clear. An example is given.
