Abstract

Electromechanical braking technology is an effective way to improve the braking response of mine hoist. Based on the analysis of mechanical disc brake of mine hoist, the control process is analyzed in detail, and then the control strategy is obtained. An automatic control system based on linear quadratic regulator and PI controller is proposed. The braking goal of self-adaptive adjustment of braking clearance and on-line adjustment of braking force is realized. The results of the experiment indicate that the brake gap adjustment time is less than 10s, stable within 1±0.2mm, and the steady-state error is less than 2%. The positive pressure of the brake has a linear relationship with the motor voltage, with a slope of 920.4 and an intercept of -1298.88. The problems of low automation and high pollution of the existing hydraulic brake have been solved, which provides a new way for the control system of electromechanical brake.
