In this paper a dual DC/DC/AC inverter with discrete non-stationary state feedback controller is presented. Neural network based control algorithm is proposed to optimal control of PMSM drive. The considered converter topology and designed control structure with discrete state feedback controllers significantly reduces the harmonics content in phase currents.
In this paper, constrained non-stationary state feedback speed controller for PMSM drive fed by VSI with SiC MOSFETs is presented and experimentally verified. The novelty of proposed approach lies in direct design of non-stationary state feedback controller for non-linear and cross-coupled model of the plant. An artificial bee colony (ABC) optimization algorithm is applied to automatic selection of...
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...
In this paper new discrete non-stationary linear-quadratic speed regulator for PMSM fed by 3-level NPC sinusoidal inverter is presented. Controlled sinus wave inverter with an output LC filter was used in order to reduce electromagnetic torque ripple of the motor. The novelty of the proposed control system consists in one state feedback controller using in order to control the angular velocity of...
