Aimed at the issues that a load angle limit function being added in permanent magnet synchronous motor (PMSM) model for predictive control, though it can prevent motor slip, the angle limit function makes the adjustment of control weight coefficients complicated, a weight coefficient-free model predictive control is proposed for PMSM with load angle limitation. This method is used to implement the model predictive control based on a dictionary approach, conduct the hierarchical sequence optimization of the objective function, and achieve the multi-objective optimization without weight coefficients. In order to verify the effectiveness of this method, the simulation and the experimental studies are made. The results show that this method can achieve the load angle limitation, and the performance of dynamic and static performance is consistent with the traditional methods. Compared to the traditional methods, the steadystate errors of torque and flux are similar, approximately 0.3 N·m and 0.005 V·s. And the elimination of weight coefficient adjustment can be omitted, there is a decrease in computational burden.
