Abstract: In order to improve the control precision of coal shearer in coal mining, a strategy based on improved artificial fish swarm algorithm for high control of Shearer drum drum is proposed. On the basis of the traditional artificial fish swarm algorithm, the strategy of step decreasing and field of view change is introduced, and the parameters of PID controller are obtained by using the inverse of ITAE as the objective function optimization. The Simulink simulation model is constructed by the transfer function of the high-speed shearer system, and compared with the simulated annealing algorithm and particle swarm algorithm, the results show that the improved artificial fish swarm algorithm has less error, more accurate control accuracy and smoother step response of the system, which provides a new method for achieving more accurate control of the shearer. It provides the basis for the efficient production of coal.
