Application of ABC Algorithm in Identification and Control of Nonlinear Systems

Abstract

Abstract:

The problem of nonlinear system identification and design of its controller were considered herein.Firstly,a new ABC optimization algorithm was introduced,which generated the initial value of optimization parameters using chaotic maps.Then the proposed algorithm was applied to estimate parameters and to design PID controller.The simulation results of nonlinear systems show that the proposed algorithm can get better convergent and identification performance than other optimization algorithms.The simulation results also show the automatic voltage regulator system can improve dynamic respond behavior using chaotic ABC algorithm PID controller,and its superior performances to other conventional methods.
