Constant Power Speed-Adjusting of Shearer Cutting Motor by Single Neuron Self-Adaptive PID Controlling

Abstract:

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.
