This paper presents a novel control technique for interior permanent magnet synchronous motors, addressing their dynamic complexity and nonlinearity. The technique involves linearizing the nonlinear model of the motor using a feedback linearization method and designing an integral state feedback controller optimized through the linear quadratic regulator. The method applies control constraints using a reference reforming technique and adopts the maximum torque per ampere strategy for reference current creation. The performance of the control technique is validated through simulations at various operating points, considering the alterations in motor parameters due to the specific operating point. To evaluate the sensitivity of the control system to uncertainties, the finite element method is employed to provide a precise model for the studied motor.
