A method to the sensorless drive scheme of permanent magnet synchronous motors (PMSM) using the reduced order observer is proposed. The control inputs that can eliminate the nonlinear term in the d-and q-axis electrical equations are introduced. Both decoupling and linearization of the model are realized. The method allows the use of linear control strategies to construct controllers and determine the stability of the system.
