this paper presents a fuzzy search controller approach along with the look-up tables, to optimize the efficiency of a pump-induction motor drive. the induction motor and the converter are modeled based on thermal loss; and for modeling the pump and the hydraulic system, which are non-linear and relatively complicated, the neural network is used. in the designed system, in order to optimize the ...

in direct torque control, the selection of an applied voltage vector is based on the measuredparameters at the beginning of the sampling period. the delay between the measurement and the application of the voltage vector is the origin of an extra torque ripple. in this paper, a new predictive controller is proposed for compensating this delay and reducing the torque ripple. the stator current i...

In the linear induction motor control system, optical grating speed transducer is susceptible to strong magnetic field interference. What's more, it may reduce integration and raise device costs. Therefore a identification method replace studied in this article. This for mainly adopts Model Reference Adaptive Method (Abbreviated as MRAS) Popov Hyperstability Theory. The research content of pape...

This paper presents a comprehensive approach for modeling and classification of air gap asymmetry inter-turn short circuit faults in ladder-secondary linear induction motors (LS-LIMs). It is based on modified Magnetic Equivalent Circuit (MEC) model incorporated with current signal-based fault detection method using convolution neural network (CNN). The feature sets the mentioned are classified ...
