Robust Stabilization of Diamond Plants with Compensators

本文给出了具有补偿器的菱形对象族鲁棒稳定的充分必要条件．本文的方法和结论可用来研究菱形对象族的其它鲁棒问题，还可为补偿器的设计提供有益的方法．

This paper presents robust stabilization criteria for a kind of structred uncertain systems-families of diamond plants. We prove that a compensator c(s) robust stabilizes a diamond plant if and coly if c(s) stabilizes all of edge plants, and in some special cases it is sufficient and necessary to stabilize all of extreme plants.About one order compensators we give the critical edge plants (≤24) and extreme plants. Our results make it possible to carry out a control synthesis via computer graphics. And methods in this peper can dial with other robustness problems.
