Multi-motor Synchronized Predictive Control Based on Mean Deviation Coupling
Aiming at the problem of low accuracy of multi-motor speed synchronous control under time delay and interference environment,a multi-motor synchronous predictive control method based on mean value deviation coupling structure was pro-posed.Firstly,the mean value deviation coupling synchronous control structure was designed by introducing the speed error and its mean value on the basis of the deviation coupling structure,which improved the control accuracy of the multi-motor synchronous control system;Secondly,the mean value deviation coupling structure was combined with the generalized predictive control algo-rithm to design the mean value deviation coupling multi-motor synchronous predictive controller,which achieved the synchronous control of the multi-motors'rotational speed under the time-delay environment.Finally,the simulation results show that the syn-chronous control strategy significantly improves the speed synchronous control accuracy of the multi-motor system under time-de-lay and interference environments,and it has the advantages of fast convergence speed of speed synchronous error and strong ro-bustness.
