Error Analysis and Optimization of Mine Hoist Control System
In order to improve the control accuracy of mine elevators and reduce rate transmission errors,this paper analyzes the main interference factors and error causes of the control system,optimizes the transmission and drag structure of the elevator frequency converter,and uses welded flanges to form a hard connection,optimizes the pin specifications,reduces the deflection,and improves the anti-interference performance of the shaft encoder.Finally,the gearbox is modified,And the speed transmission of the optimized control system was monitored,and it was found that the synchronization rate was significantly improved,the transmission error was reduced,and the control effect was significant.
