Constant Power Speed-adjusting of Shearer Cutting Motor by Single Neuron Self-adaptive PID Controlling

摘要

In order to suit better for variations of coal and rock with different properties, solve the problem of big fluctuation of a cutting motor power, and ensure the durable high-efficient, high-energetic working of a shearer, a constant power speed-adjusting system of shearer cutting motor is designed based on the theory and the method of single neuron self-adaptive PID controlling, the system effects constant power function of shearer cutting motor by adjusting continually the shearer's haulage speed.A systematic simulation model is build by using the Matlab/Simulink, and the experiment shows: the speed-adjusting system of single neuron self-adaptive PID controlling has following advantages by comparing it with a traditional controlling method: adjustment time of haulage speed decreases by 0.6s, overshoot and adjustment time of the cutting motor power lower by 2.4％ and 0.27s respectively, which improves the working efficiency of the shearer by a rapid reaction speed and a good controlling property.
