Multiobjective Optimization of PID Controller of PMSM [PDF]
PID controller is used in most of the current-speed closed-loop control of permanent magnet synchronous motors (PMSM) servo system. However,Kp,Ki, andKdof PID are difficult to tune due to the multiple objectives. In order to obtain the optimal PID parameters, we adopt a NSGA-II to optimize the PID parameters in this paper.

Permanent Magnet Synchronous Motors (PMSM). Parameters influence on the synchronization Process of a PMSM [PDF]
This paper deals with the finite element estimation of cogging torque oscillations that occur in multi-pole permanent magnets synchronous wind generators. The numerical analysis is carried out using a 2D plane-parallel finite element model of the machine and afterward a more elaborated 3D model able to take
