This work deals with Backstepping control strategy for permanent magnet synchronous motor drive, using load torque observer. The proposed study uses a modified motor model with new variables, dynamic separation and Luenberger load torque observer. This paper proposes a precise calculation method for controller and observer parameters based on response time and damping coefficient. Validation is performed using Processor In the Loop technique and code generation from Simulink. Results show that Backstepping works well by adding disturbance observer so accuracy is ensured. In addition, response time is respected due to the precise controller design.
