【Abstract】 The efficiency improvement and intelligent development of underground auxiliary transportation in colliery put forward the requirement of precise halting for the locomotive.In the paper,the dynamic model of precise halting of the locomotive was established,and its driving force and running resistance were analyzed.In addition,the fuzzy PID double closed-loop vector control system for the PMSM (permanent magnet synchronous motor) was designed,thus the precise halting of the locomotive at various speed,halting distance,slope and load condition was realized.Finally,Simulink was applied to simulate the precise halting process,and the simulation results showed the proposed precise halting method met the requirement of halting precision.更多还原
