Ann-based static slip power recovery control of wrim drive

Abstract EN

This paper presents a novel ANN-based slip power recovery drive system of WRIM, which estimates the appropriate firing angle of the thyristors in the inverter circuit for any given operation condition.

Adjusting the speed or electromagnetic torque of the WRIM can be achieved by controlling the slip energy through slip power recovery in rotor side.

The performance characteristics of drive system are determined using simple DC equivalent circuit.

The obtained results are satisfactory and promising.

The proposed controller operates on open loop, so it does not require speed sensor.

Another advantages of such controller are it’s simplicity of the configuration and high accuracy.

The effectiveness of these controllers is demonstrated for different operation conditions of the drive system.
