Abstract :
The decoupling control method of permanent-magnet synchronous motor(PMSM) is proposed by using exact linearization via state variable feedback. The exact linearization conditions of multi-input and multi-output are discussed with differential geometry method based on the mathematic model of PMSM. The PMSM linearization and decoupling controller design are completed by coordinates transformation and state variable feedback transformation. The decoupling controller was designed and the control results are researched by computer simulation. The simulation results show that the decoupling method this paper proposed is feasible and the multi-input multi-output linearization of PMSM using state variable feedback exact linearization method can obtain satisfactory effect.
