Outline
Aiming at the problem of synchronous control of each segmented motor in the multi-point segmented combined drive system with continuous lifting of large capacity in deep shaft, based on the traditional deviation coupling control method, an improved deviation coupling control strategy was proposed using the double closed-loop control of speed and torque. The numerical model of synchronous control of six-motor segmented combined drive continuous lifting system was built, and the synchronous tracking performance of traditional deviation coupling control and improved deviation coupling control under different starting load torque and steady-state load disturbance of segmented combined drive system with continuous lifting was compared and analyzed. The results show that compared with the traditional deviation coupling control system, the improved deviation coupling control strategy can effectively solve the problem of asynchronous speed in the start-up process of the multi-point segmented combined drive system with continuous lifting of large capacity in deep shaft. At the same time, the synchronous tracking performance and dynamic response performance of the system in the start-up stage and under steady-state disturbance are improved, and the feasibility of the application of the improved deviation coupling control in the multi-point segmented combined drive synchronous control system with continuous lifting is verified.
