This paper presents a robust nonlinear generalized predictive control (RNGPC) strategy applied to a permanent magnet synchronous motor (PMSM) for speed trajectory tracking and disturbance rejection. The nonlinear predictive control law is derived by using a newly defined design cost function. The Taylor series expansion is used to carry out the prediction in a finite horizon. No information about...
This paper presents robust self-tuning maximum torque per ampere (MTPA) control algorithm for an interior permanent magnet synchronous motor (IPMSM) drives. Proposed algorithm utilizes conventional control scheme, where speed controller produces stator current command signal for the MTPA block. That block decomposes commanded current Is into its components along direct and quadrature axes id and iq...
The real-time torque calculation and dynamic modeling have been the difficulties in the motion control of the permanent magnet spherical stepper motor. Based on the presented continuous trajectory tracking control mode, a simplified torque calculation method and the non-linear system dynamic model have been proposed. The perturbation of the system parameters, the model error and the external disturbance...
