This paper introduces a nonlinear control scheme based on exact feedback linearization (FBL) and predictive concept to control the permanent magnet synchronous motor (PMSM). The principal contribution of this work is the exploitation of discrete state model to generate the predicted trajectories and, the calculation of the Brunovsky form feedback stabilization which correspond to the linear part of...
The non-interacting control method of permanent-magnet synchronous motor (PMSM) is proposed by using exact linearization via state variable feedback. The conditions of exact linearization are discussed with differential geometry method based on PMSM mathematic model. The PMSM linearization and non-interacting control design had been completed in the entire state variable space by state coordinates...
Feedforward-feedback control can be used to achieve torque ripple minimization or error minimization between the reference and the output. Theoretically, if the inverse transfer function of the plant is known, it is possible to achieve zero error through feedforward control. In this paper, the references (acceleration, velocity and position) are designed so that they can be used as inputs to the feedforward...
This paper proposes a novel control strategy for IPMSM drive system. The proposed single-phase to three-phase power converter does not require a reactor and an electrolytic capacitor at dc-link, and obtains unity input power factor. The proposed control method improves the source current waveform at any load conditions by using the feedback control. The proposed control system is constructed by using...
A nonlinear adaptive robust speed tracking controller is presented for a three-phase synchronous reluctance motor (SynRm) considering the control strategy of maximum torque control (MTC) related to this motor. Ignoring the motor iron losses, the proposed controller is designed based on combination of input-output feedback linearization (IOFL) control and adaptive sliding mode technique. The proposed...
This paper proposes a novel flux-weakening control algorithm of an interior permanent magnet synchronous motor for 'quasi' six-step operation. The proposed method is composed of a feed forward and a feedback path. The feedforward path consists of 1-dimensional look-up table, and the feedback is based on the difference between the reference voltage updated by current regulator and the output voltage...
This paper introduces the structure of synchronous reluctance with permanent magnet (SR-PM) motor and its principle of direct torque control (DTC), especially focuses on characters of DTC in SR-PM motor. Then the (position/speed) sensorless strategy of SR-PM motor is studied. The key point of sensorless control is estimating the torque angle delta precisely. This paper presents two different compensating...
