In this paper a new neural network based adaptive state feedback controller used to torque ripple minimization for PMSM is presented. A simple adaptation algorithm is proposed to determine an appropriate value of inverter DC voltage and, in consequence, non-linear coefficients of the controller. The novelty of the proposed approach lays in precisely control the level of inverter DC voltage required...
This paper describes a new linear-quadratic non-stationary position regulator (LQR) for the permanent magnet synchronous motor servo-drive with sinusoidal voltage source inverter. The LC filter is used in order to reduce an electromagnetic torque ripple and to improve the servo-drive performance. Modelling process of a motor and LC filter was discussed. An internal input model was introduced to proposed...
This paper presents a design approach of a position controller for permanent magnet synchronous motor (PMSM) servo-drive. Firstly the well know nonlinear mathematical model of PMSM is evaluated to a linear form by introducing new variables. The state space new model presented in rotates ortogonal reference frame is decupled in means of equation in d and q axis. An internal input model have been used...
