Summary: | The invention discloses a nine-sector direct torque control method based on early opening, and belongs to the field of motor control. As the switched reluctance linear motor is simple in structure, low in cost, large in starting electromagnetic force and small in starting current, the switched reluctance linear motor is more and more applied in the industrial field. However, the problems of electromagnetic force pulsation and noise are serious due to a doubly salient structure and work in a nonlinear region, and in order to solve the problems, a three-phase double-side SRLM is used as a prototype, and RT-LAB is used as a controller. Firstly, similar sectors are combined for traditional twelve sectors, a nine-sector partitioning method is provided, then a solution for opening in advance is provided for the problem that the electromagnetic force pulsation at the minimum inductance of each phase is large, and it is found that the suppression effect on the electromagnetic force pulsation is obvious. Finally, the |
