摘要

In order to suppress the impact of a loads-induced gear dynamic load of a drum shearer cutting transmission system, an active torque compensation control method is proposed in this paper based on the active disturbance rejection and adaptive neuro-fuzzy control technologies. Using the speed difference between the motor rotor and the first stage gear as a feedback state variable, an active disturbance rejection torque compensation controller is firstly designed for suppressing the dynamic load of the electromechanical transmission system. The controller uses the speed difference as the tracking control target and sets it to a zero value, thereby transforming the dynamic load suppressing problem into a trajectory tracking problem. Secondly, the active disturbance rejection controller parameters are tuned based on the adaptive neuro-fuzzy control technology. Therefore, the torque compensation can be realized adaptively in accordance with the various cutting conditions. Finally, the suppression effect on the dynamic load of the transmission system under continuous impact conditions with different load mutation rates is analyzed based on the proposed control method. Simulation results indicate that the proposed method exhibits a good control effect in suppressing the dynamic load and an improved adaptive ability to the complex and changeable working conditions. The proposed method also can be useful for the electromechanical transmission systems with similar structure applied in other areas.
