摘要: In this paper, two coupling permanent magnet synchronous motors system with nonlinear constraints is studied. First of all, the mathematical model established according to engineering practices, in which dynamic motor and effect between are considered. order keep synchronization, a synchronization controller based on load observer designed via cross-coupling idea interval matrix. Moreover, speed, position current signals all taken as self-feedback signal well cross-feedback proposed controller, conducive improving dynamical performance system. The control strategy verified by simulation Matlab/Simulink program. results show that method has better performance, especially than conventional PI controller.
