- Abstract
To solve the problem that harmony search (HS) algorithm is easily trapped into local optimal, a novel improved harmony search (IHS) algorithm is proposed. Search strategy are redefined in IHS. In order to increase the diversity of harmony in harmony memory and enhance exploration, the concept of entropy is introduced for generating new harmony at the beginning of the optimization. When the algorithm is at a standstill state during the process of optimization, the information of harmony memory is considered and the basic theory of firefly algorithm is introduced so as to accelerate the convergence speed of the algorithm and improve the algorithm's intensification ability. The proposed algorithm is tested on several classic functions and PID control problem, and the simulation results show that IHS has better performance.
