Sensorless Motor Drives with Predictive Current Control
Hardware complexity of a motor drive can be reduced by estimating controls rather than measuring using sensors. In this way the corresponding sensors are eliminated and the system becomes more robust. This article is about speed control of a sensor less induction motor with predictive current controller technique. This particular speed control technique does not require direct measurements of m...
متن کاملModel Predictive Control of A Speed Sensorless Linear Induction Motor Drive
In this paper, the model predictive control (MPC) technique has been used to control the speed of the linear induction motor (LIM) drive. The mathematical model of the LIM has been described in the stationary frame. The longitudinal end effects of the linear induction motor are taken into account as external load.The concept of field orientation is used to decouple the mover speed from the seco...
متن کاملSpeed-Sensorless Nonlinear Predictive Control of a Squirrel Cage Motor
-This paper presents a nonlinear generalised predictive control scheme for a squirrel cage motor without speed sensor. Some of the difficulties faced are due to uncertainties in the parameters measurements, high cost to obtain state measurements in addition to the inherently non-linear behaviour. The control scheme presented is composed of a positioning predictive control and an open loop obser...
متن کاملSensorless Indirect Field Oriented Control of Single-sided Linear Induction Motor With a Novel Sliding Mode MRAS Speed Estimator
This paper proposes a new sliding mode control (SMC) based model reference adaptive system (MRAS) for sensorless indirect field oriented control (IFOC) of a single-sided linear induction motor (SLIM). The operation of MRAS speed estimators dramatically depends on adaptation mechanism. Fixed-gain PI controller is conventionally used for this purpose which may fail to estimate the speed correctl...
متن کاملSeveral Speed Sensorless Methods of Induction Motor Control
This paper deals with different techniques to estimate the speed intended to the induction motors field oriented controlled without a shaft sensor. The information on the rotor speed is extracted from the stator terminal measurements (voltage and current). Open loop estimators and closed loop observers are used for this purpose and compared in term of their robustness against the variation of t...
