Algebraic synthesis of dependable logic controllers

Algebraic synthesis of dependable logic controllers

This paper presents an algebraic method to synthesize control laws for logical system controllers. The starting point is a set of functional and dependable requirements expressed with algebraic relations or state models. We propose to synthesize control laws by solving a Boolean equation which represents all the requirements. The mathematical results that we have obtained allow to establish the...

Designing dependable logic controllers using algebraic specifications

Formal methods can strongly contribute to improve dependability of logic controllers during design, by providing means to avoid flaws due to designers' omissions or specifications misinterpretations. This article presents a formal synthesis method that is aimed at obtaining the control laws of a logic system from specifications given in natural language. The formal framework that underlies the ...

Designing dependable logic controllers using the supervisory control theory

In this paper we deal with the problem of designing a controller for a discrete event system. We argue that the classical approach of supervisory control theory (SCT) can be used as an essential step of such a procedure. However, some of the features that make supervisory control an attractive paradigm to solve theoretical problems are often a major source of difficulty in implementing a contro...
