Abstract: Permanent magnet synchronous motor (PMSM) has the advantages of simple torque control, small size, high efficiency and energy saving, and has gradually become the mainstream of the development of new elevator traction systems. Based on the mathematical model, this paper applies SVPWM modulation technology to control PMSM, applies generalized predictive control to the current link, and constructs a predictive PI current regulator. The simulation analysis and practical application results show that compared with the traditional current regulator, the control performance of the predictive PI regulator is greatly improved.
