Abstract
In view of problems of asynchrony of torque and speed existed in traditional synchronous control strategy of dual-motor drive based on current differential closed-loop as well as mechanical torsional vibration caused by load disturbance is not considered,a synchronous control strategy of dual-motor drive for mine-used belt conveyor based on speed differential closed loop was put forward taking dual-motor drive system of mine-used belt conveyor as research object.The current signals of dual-motors were compensated by using rotate speed error between dual motors,if the rotate speed error of dual motors was produced,the rotate speeds were adjusted by adjusting currents (torque) of dual motors,so as to keep the rotate speeds in synchronization.For torsional angle of mechanical axis caused by load disturbance,a torsional vibration suppression strategy was proposed:torsional angle equation was allocated rationally to attenuate the torsional angle rapidly,so as to achieve good suppression effect for torsional vibration.Matlab/Simulink simulation results demonstrate reliability of the control strategy.关键词
