The mine hoist automation control accuracy is not high and the control performance is not stable. The particle swarm optimiza tion algorithm is used to automatic control system, the defects of early maturity and algorithm parameters are difficult to determine, parame ter calming effect is poorer. In view of the above disadvantages, proposed the bacteria foraging particle swarm optimization algorithm of the mine automation control algorithm, improved algorithm to mine automation control input variables as main parameters in the algorithm, u sing bacterial chemotaxis, reproduction and disperse process of particle swarm optimization algorithm is optimized, and then based on particle swarm optimization algorithm framework particle update, effectively improve the global solving ability of particle swarm optimization algorithm, to solve the mine hoist control accuracy is not high the problem of poor stability. The simulation results show that the proposed algo rithm has good stabilization effect, control precision is 24.30% higher than that of traditional algorithm and the algorithm, has good applicability.
