Synergetic Synthesis of Adaptive Control of an Electro-pneumatic System

Abstract

The synthesis of control law is still a complex task which requires a creative approach to its solution. A significant expansion of the functionality of the pneumatic drive is achieved by introducing a precise organization of control of its elements into the pneumatic system. Currently, different researches are made in this field using the classical linear law control, the optimal control methodology, as well as the modern apparatus of fuzzy logic and neural networks. The aim of this work is to develop an astatic nonlinear synergistic controller to suppress disturbing effects arising in electro-pneumatic systems. The synthesis of control actions was carried out by means of the method of analytical design of aggregated controllers, which is a part of the concept of synergetic control theory. The control law obtained analytically by means of the joint solution of the introduced macro-variable and functional equations guarantee the asymptotic stability of the closed system, as well as the achievement of the desired control goals.
