چکیده
Induction motor drive control and estimation is a wide subject. The market for variable speed drives has grown dramatically in the last few years. Manufacturers have recognized importance of not only managing or torque range, but also reducing power consumption. This necessitates development new algorithms schemes to include these solutions. Indeed, estimate must be employed one more regions scheme, depending on objective. concept, as well most common methodologies, investigated. Currently, many tools can used evaluation rotor without sensor. By modern signal processing methods, it possible implement an scheme with possibility monitoring currents voltages. Therefore, this paper, concept currents, fluxes based extended Kalman filter proposed. ratio theoretical residual actual residual, measured noise covariance matrix recursively corrected online make gradually approach real level. So that performs optimal estimation, improves accuracy estimation. effect load change was studied. Simulation experimental results show proposed improved adaptive estimator strong ability suppress random measurement noise. simulation prove towards state induction at different levels. It accurately good anti-error meet needs project.

متن کاملSpeed Observer Design for Linear Induction Motor Drives
In this paper, a neural network model reference adaptive system speed observer is designed, which can be used in speed control of linear induction motors (LIMs). Dynamical equations of LIM have been considered accurate. In other words, the end effect and the electrical losses of the motor have been included in the motor equivalent circuit. Then equations of the reference model and adaptive mode...
