Hierarchical Hybrid Control Synthesis and its Application to a Multiproduct Batch Plant

Abstract

This paper presents a hierarchical approach to hybrid control systems synthesis. It is set in a general behavioural framework and therefore allows a combination of continuous and discrete layers in the resulting overall controller. Compared to unstructured approaches, it drastically reduces computational complexity and hence enlarges the class of continuous-discrete control problems that can be addressed using methods from hybrid systems theory. The potential of our approach is demonstrated by applying it to a multiproduct batch control problem.

Keywords: Hybrid systems, hierarchical control, discrete abstraction, multiproduct batch plant.
