The Application And Research Of The Mineral Hoist DTC System Based On ACA

The mine pit is often called for the throat of the mine by the miners. The mineral hoist is widely used in the production of the coal, the metallurgy and other mineral. It is one of the essential mineral transportation equipments. It shoulders all transportation duty in the mine pit. Therefore the mineral hoists'technical level and reliability is not only related with the mine pit productivity and the productive plan management, but also related with each miner's safety. And the velocity modulation performance is the important target of the mineral hoist quality. For several years each manufacturer doesn't care the velocity modulation and the AC velocity modulation equipments. The control technology of the mineral hoist is laggard continuously. Therefore it is an urgent work that analyses the present situation and prospects of the mineral hoists AC velocity modulation equipments and promotes product which connects rails with the overseas advanced technology level.In view of the high failure rate and the low safety coefficient in the mineral hoist, it is already imperative to use the advanced control technology to the mineral hoist. In order to enable the mineral hoist control system to have the advanced control performance and the redundant reliability, the article uses the direct torque control method. The direct torque control method has novel control thought, the simple structure and the fine dynamic and static properties. But the direct torque control system's own limitation limits its application on the mineral hoist.This article introduces the ant colony algorithms into the direct torque control system to apply it to the mineral hoist control system. It has a certain research value.
