In this paper, a simplified mathematical model of the motor for a vacuum pump is established and the transfer function is introduced, which weakens the multivariable, strong coupling and nonlinear characteristics of the motor system. According to the basic principle of the relative coupling control strategy, the neural network Proportion Integration Differentiation (PID) is introduced as a speed compensator in this system. It effectively improves the synchronization and anti-interference ability of the multi motor.}, type={Article}, title={Multi motor neural PID relative coupling speed synchronous control}, URL={http://www.czasopisma.pan.pl/Content/115089/PDF/05_AEE_1_2020.pdf}, doi={10.24425/aee.2020.131759}, keywords={fuzzy control, multi motor synchronous control, neural PID, relative coupling control, vacuum pump}, }
