摘要
针对非线性系统辨识和控制器的设计,提出一种混沌映射产生初值的人工蜂群优化算法,并将该算法应用于非线性系统中的参数辨识和PID控制器的设计。参数辨识的仿真结果表明,基于混沌映射理论的人工蜂群优化算法比其他传统的算法具有更好的收敛特性和辨识性能;自动电压调节系统的仿真结果表明,基于混沌人工蜂群优化的PID控制自动电压调节系统是可行性的,且具有良好的动态调节性能。
The problem of nonlinear system identification and design of its controller were consid- ered herein. Firstly, a new ABC optimization algorithm was introduced, which generated the initial val- ue of optimization parameters using chaotic maps. Then the proposed algorithm was applied to esti- mate 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 optimiza- tion 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.
