PID Controller Parameter Optimized by Reformative Artificial Bee Colony Algorithm

Abstract

The PID parameters determine the PID controller performance. A reformative artificial bee colony (RABC) algorithm is proposed for the PID parameter optimization problem. The algorithm balances the exploitation capability and exploration capability of the ABC algorithm by introducing a global optimal solution and improving the food source probability. The proposed algorithm is validated by simulation with six benchmark functions, and the results show that the RABC algorithm has higher search accuracy and faster search speed than other variants of the artificial bee colony algorithm. The RABC algorithm‐optimized PID controller has better control with minimum overshoot and fast response, as verified by comparison with PSO‐PID, DE‐PID, and GA‐PID methods in three typical systems.
