Predictive dq Current Control of an Induction Motor

2021 25th International Conference on System Theory, Control and Computing (ICSTCC), 2021
In this paper, a predictive control algorithm for the current system of an induction machine (CS-IM) is presented, developed by using the field orientation control (FOC). The CS-IM is modeled in the dq rotor reference frame. By adopting the hypothesis of considering the synchronous angular speed as a known parameter, the CS-IM may be approached by the ...

Prediction and Control of Transformer Inrush Currents

IEEE Transactions on Magnetics, 2015
In this paper, we propose a dynamic model of the electrical transformer suitable for the numerical prediction of the inrush currents due to the arbitrary initial excitation of a transformer after a switch-OFF. In particular, the proposed model can be helpful to control strategies to avoid a transient current overshoot, based on the prediction of the ...

Predictive Current Control Using Identification of Current Ripple

IEEE Transactions on Industrial Electronics, 2008
This paper presents a new time-discrete predictive current control for permanent-magnet synchronous motor (PMSM) which follows a reference step in two sampling periods. The control stands out by using a permanent identification which allows fast control even if the motor parameters are changing.

Predictive current control of voltage source inverters

IECON'01. 27th Annual Conference of the IEEE Industrial Electronics Society (Cat. No.37243), 2002
A new current controller for a voltage source inverter based on calculation of an electromotive force is presented in this paper. Practical aspects of realizing the new controller in a system with a signal processor are considered. Delays introduced by measurements are taken into consideration.

A Geometrical Interpretation of Current Transient Responses to Predict Current Gradients for IPMSM Model Predictive Control

IEEE Transactions on Industrial Electronics, 2021
The ability to use actuator and load models online in combination with experimental data becomes increasingly important in future electrical drives. Among the applications of such online model in torque and flux controllers, model predictive control (MPC) has gained increasing interest, allowing to deal in real time and in a suboptimal way with drive ...

A Robust Predictive Current Controller for PMSM Drives

IEEE Transactions on Industrial Electronics, 2016
High-performance current control is required to obtain a smooth output torque in permanent-magnet synchronous motor (PMSM) drives. In this manner, a new discrete-time robust predictive current controller is presented for PMSM drives. Controller and current prediction schemes are designed based on the dead-beat structure.

CURRENT HARMONIC COMPENSATION USING PREDICTIVE CONTROLLERS

Journal of Circuits, Systems and Computers, 2004
The power quality has become a major concern since late 1980's. There has been increasing interest in studying power quality problems, one of which is the existence of the current/voltage harmonics. In order to eliminate these harmonics, different methods have so far been proposed and developed.
