Shearer Drum Height Adjustment Strategy Based on Automatic Control

Mainly studies the shearer drum height adjustment strategy based onautomatic control. The first loop shearer regulating system transfer function is established, through the closed loop transfer function ofthe shearer drum tune the state space equation system, based on the shearer drum height adjustment controller was designed in the system, the sliding mode variable structure controller, the shearer drum adjustable slip plane switching function system the. On the basis of the shearer hydraulic system simulation.
