DESIGN OF AN ERROR-BASED ROBUST ADAPTIVE CONTROLLER USING GA BASED PID CONTROLLER

摘要

Design of an adaptive controller for complex dynamic systems is a big challenge faced by the researchers. In this paper, we propose a novel method for the design of an error- based robust adaptive controller to make the system response reasonably fast with no overshoot. Here the control action is designed by introducing the notion of 'error-based adaptive controller' (EB-AC) by using GA based PID technique we design feedback controller. This approach for formulating the adaptive controller yields a very fast response with better time response characteristics. In this paper, we present an error-based robust adaptive control design methodology for a linear system and different comparisons are made in MATLAB/ SIMULINK.
