6th IFAC Symposium on System Structure and Control (SSSC)

In order to design efficient, algorithms that work on the set of controllers that fulfill a given property, e.g., stability, it is important to have an operation that preserves that property, i.e., a suitable blending method. In this paper we show that one can define a special blending that preserves stability mid it is defined directly in terms of the plant and controller, without, the necessity to use any factorization. Moreover, as an interesting side effect, of these investigations, an operation is given that leaves invariant the strongly stabilizing controllers and defines a group structure on them, too. The properties of the newly defined operation are illustrated through the special case of static state feedback controllers. Besides its educative value the presentation also provides a possible tool for the algorithmic development. 2016, IFAC (International Federation of Automatic Control) Hosting by Elsevier Ltd.

Feedback stabilization: from geometry to control

Youla parametrization of stabilizing controllers is a fundamental result of control theory: starting from a special, double coprime, factorization of the plant provides a formula for the stabilizing controllers as a function of the elements of the set of stable systems. In this case the set of parameters is universal, i.e., does not depend on the plant but only the dimension of the signal spaces. Based on the geometric techniques introduced in our previous work this paper provides an alternative, geometry based parametrization. In contrast to the Youla case, this parametrization is coordinate free: it is based only on the knowledge of the plant and a single stabilizing controller. While the parameter set itself is not universal, its elements can be generated by a universal algorithm. Moreover, it is shown that on the parameters of the strongly stabilizing controllers a simple group structure can be defined. Besides its theoretical and educative value the presentation also provides a possible tool for the algorithmic development. © 2017

Feedback stabilization: the algebraic view

21st IFAC World Congress on Automatic Control - Meeting Societal Challenges

作者： Szabo, Z. Bokor, J. Inst Comp Sci & Control Budapest Hungary

Based on an abstract algebraic setting we provide an elementary derivation of the Youla-Kucera parametrization of stabilizing controllers and also an alternative, coordinate free, approach of the problem. For this latter case, in contrast to the Youla-Kucera approach, the parameter set is not universal but its elements can be generated by a universal algorithm. We also emphasise the natural continuity property of this parametrization compared to the Youla-Kucera case. Extending the framework to the LFT loops we show by using elementary tools that every controller which stabilizes the interior loop of the generalized plant also stabilizes the LFT loop.

Blending for H∞ performance: a group theoretic approach

引用

IFAC-PapersOnLine 2015年第14期48卷 186-191页

In order to design efficient algorithms that work on the set of controllers that fulfill a given property, e.g., stability or a norm bound, it is important to have an operation that preserves that property, i.e., a suitable blending method. Concerning stability, a traditional approach is to use the Youla parametrization and the corresponding parameters as a starting point. While this method guarantees stabilizability as the invariant property for the fairly large class of strictly proper plants, there are also other solutions to the problem. The authors already provide a detailed analysis for feedback stability placing the controller blending problem in a general setting by pointing to the basic global geometric structures that are related to well-posedness and feedback stability. In this paper these efforts are continued and the group structure corresponding to performance problems, e.g., those related to a suboptimal H ∞ design, is presented. Besides its educative value the presentation provides a possible tool for the algorithmic development.
