Synthesis of a relay regulator with fuzzy switching times on the basis of a macro-variable

Synthesis of a relay regulator with fuzzy switching times on the basis of a macro-variable A method for the identification of the dynamic regimes of a controlled object on the basis of an analysis of a macrovariable of the form, square of the norm of the variable states, and its time derivatives is proposed. Fuzzy if-then rules for reversal of a relay control are constructed on this basis. Based on the total number of positions of the relay, all possible regimes are divided into “correct” and “incorrect.” The control strategy consists in control reversal upon the appearance of an “incorrect” motion regime. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Automatic Control and Computer Sciences Springer Journals

Abstract

A method for the identification of the dynamic regimes of a controlled object on the basis of an analysis of a macrovariable of the form, square of the norm of the variable states, and its time derivatives is proposed. Fuzzy if-then rules for reversal of a relay control are constructed on this basis. Based on the total number of positions of the relay, all possible regimes are divided into “correct” and “incorrect.” The control strategy consists in control reversal upon the appearance of an “incorrect” motion regime.
