Optimization of Induction Motor Equivalent Circuit Parameter Estimation Based on Manufacturer’s Data

Estimation Of parameter For Induction Motor Drive

Generally speed measurement is done with sensor, but disadvantage of sensor is difficult to measure speed at low speeds with sensor. These difficulties are eliminated by using sensor less Flux Orientation Controlled (FOC) . This paper proposes a Model Reference Adaptive System (MRAS) for estimation of rotor speed in FOC. An Induction motor is developed in stationary reference frame and Space Ve...

ARMA model parameter estimation based on the equivalent MA approach

The paper investigates the relation between the parameters of an autoregressive moving average (ARMA) model and its equivalent moving average (EMA) model. On the basis of this relation, a new method is proposed for determining the ARMA model parameters from the coefficients of a finite-order EMA model. This method is a three-step approach: in the first step, a simple recursion relating the EMA ...

Vi Based Parameter Identification of Induction Motor

This paper considers the problem of parameter identification and speed estimation of a three-phase squirrelcage induction motor using Virtual Instrumentation. LabVIEW is the graphical development environment for creating flexible and scalable test, measurement, and control applications rapidly and at minimal cost. With LabVIEW, interface with real-world signals, analyze data for meaningful info...

Off-Line Parameter Estimation of Induction Motor Based on a Multitime Scale Approach

The paper presents a method for parameters estimation of squirrel cage induction motor. The statespace model of the system can be decomposed in two quasi-decoupled systems because the dynamic of electrical system and the one of the magnetizing system are different. It is used a multitime scale decomposition to obtain reduced operational reactances. In the experiments the induction machine is at...
