双频驱动双转子振动系统同步控制研究
The Investigation on Synchronous Control of Dual-Rotor Vibration System Excited with Double-Frequency
摘要
Abstract
Aiming at the problem of slurry overflow caused by the inherent dynamic characteristics of traditional self-synchronous vibration screen in petroleum engineering,a novel controlled synchronous vi-bration system driven with double-frequency and dual-rotor is proposed,which can guarantee that the ma-terials on screen mesh are subjected to the different excitation frequencies in a single cycle,and the motion state is more active to reduce the probability of screen mesh blocking.Firstly,in this paper,the energy con-version process of dynamical model is analyzed,the motion differential equation of vibration system is de-rived by applying Lagrange's formula.Secondly,equivalent sliding mode control algorithm is combined with the master-slave control structure to realize the stable dual-frequency control synchronization motion.Meanwhile,the output torque equation and the load torque equation of each motor are obtained by using mathematical model of AC motor.Subsequently,the suitable sliding mode functions are selected for the two motor control systems,and the control law expressions of velocity tracking controller and phase track-ing controller are designed in detail.Then,the saturation function is introduced to replace the sign function in the sliding mode controllers,which can improve the operation accuracy of controller and reduce the chat-tering amplitude of the control variable during the process of approaching.Finally,according to the pro-posed control strategy,an electromechanical coupling synchronization control model with dual-motor and double-frequency actuation is constructed.Furthermore,feasibility and robustness of the control theory are verified by presetting different control conditions of the vibration system.关键词
