Since the traditional PID parameter tuning method has become more and more time-consuming,and is hard to meet the control requirements,a new method of optimizing PID control parameters by using firefly algorithm is proposed in this paper,and a parameters optimization model based on Simulink was designed to carry out the simulation calculation. The results show that PID controller parameters optimized with the firefly algorithm has short step response time and stable tracking pro-cess,and proves that it is feasible to adopt the firefly algorithm in PID parameter optimization.
