Application of different controller schemes for analogous systems

Abstract

This paper presents an attempt of implementation different controller units for selective analogous system. To realize this approach an electromechanical system involving spring and damper mechanical system associated with its analogy electrical system have been used. The combination of this analogy electrical circuit consists of series configuration involved resistor and capacitor elements. The mathematical models of these analogies systems have been obtained based on the essential of mechanical and electrical laws for each system. These mathematical models have been used to obtain the required transfer functions of the proposed analogous control system. Different controller units such as the conventional proportional, integral, derivative (PID-controller) and in the selective analogous control system. Each of these controller units has been designed to work independently and provide the demand control action for the simulation process that has been done via Matlab software package. A comparison between the obtained results has been carried out to investigate the best performance of the suggested analogous control system.
