Control of asynchronous drive of mine hoisting machines during deceleration and pulling periods

Abstract

Automation of mine hoisting installations with asynchronous drive is usually complicated during the deceleration and creep stage, when the hoisting conveyance must pass a strictly defined path, approach the dumping curves with a certain minimum speed and move at this speed until the completion of the hoisting cycle regardless of the magnitude and sign of the end-of-stroke load.
