This paper presents estimation of d-axis and q-axis inductance of an interior permanent magnet synchronous motor (IPMSM) by using an extended Kalman filter (EKF). The EKF is widely used for control applications including the motor sensorless control and parameter estimation. The motor parameters can be changed by temperature and air-gap flux. In particular, the variation of the inductance affec...

The back emf harmonics of a permanent magnet (PM) synchronous motor is a major source of torque ripple. For torque control applications including column fitted MDPS (motor driven power steering) systems, it is essential to reduce the mechanical vibrations due to torque ripples at low speeds. In this paper, a torque ripple reduction algorithm for interior PM synchronous motors is proposed. The h...

The main objective of this paper is to show a methodology to implement a Maximum Torque per Ampere Strategy (MTPA) in an Interior Permanent Magnet Synchronous Machine (IPMSM). IPMSM ́s have been broadly used on industry in the last years for having excellent dynamic performance and high power density. In this article, vector control and MTPA theory and criteria are firstly detailed. Then, the ma...

Interior permanent magnet synchronous motors (IPMSMs) are used for various applications and high efficiency control is required. Maximum torque per ampere (MTPA) a method to IPMSMs with efficiency. However, since the motor parameters vary magnetic saturation, MTPA cannot be easily realized. Here in, we propose fully online automatic method. To find point while driving motor, it necessary predic...
