Abstract: With the increasing depletion of shallow coal resources and the efficient and intensive development of coal mines, the mine lifting system is gradually moving towards ultra deep wells and heavy loads. The traditional mine lifting system is difficult to solve the problems of reduced lifting efficiency and reliability caused by increased lifting depth, elongation of steel wire rope, and increased load. Based on the principle of linear motor vertical propulsion technology, a linear motor and steel wire rope composite lifting system was designed, with a focus on simulation and experimental research on the heterogeneous multi motor collaborative driving control strategy of the composite lifting system. Firstly, based on the current largest 50 t coal loading skip in the coal mining field, an incremental design was carried out for the linear motor and steel wire rope composite lifting system, including the initial structural layout of the linear motor and the design of skip load increase and lifting; Secondly, the control strategies of PMSM and PMLSM are selected, the simulation models of single motor vector closed loop control and Multiple PMLSMs synchronous control are established respectively, and simulation analysis was conducted on the synchronous control performance of multiple linear motors; Thirdly, "T−v control strategy" and "F−ω control strategy" refers to two different multi-motor cooperative driving control strategies, which respectively establish the electromechanical coupling dynamics model of the composite hoisting system under two control strategies, and simulate and analyze the system dynamic characteristics of the two cooperative control strategies according to the actual application conditions of the hoisting system; Finally, the principle prototype of the combined lifting system of linear motor and wire rope is developed, and the feasibility and effectiveness of the collaborative control strategy of rotating motor and linear motor are verified through laboratory tests. The linear motor and steel wire rope composite lifting system could increase the coal load by an additional 34% on the basis of the original steel wire rope lifting system to meet the high-efficiency lifting needs of coal mines. By comparing the T−v control strategy and the F−ω control strategy through simulation experiments and prototype experiments, it could be concluded that under the T−v control strategy, PLMSM serves as the speed control object of the lifting system, while PMSM only needs to maintain a constant torque for the lifting system; The improvement system has the advantages of high precision in collaborative control of heterogeneous motors and small amplitude of tension changes in steel wire ropes. Under the F−ω control strategy, PMSM, as the speed control object of the lifting system, although has the disadvantage of large speed synchronization error of heterogeneous motors, multiple PLMSMs only need to provide constant thrust for the lifting system, which could simplify the control structure of the composite lifting system and is suitable for low-cost scenarios with low precision requirements for collaborative control.
