Abstract

Abstract

Start characteristics and electro-hydraulic servo control characteristics of CST for scraper conveyor were analyzed, compositions and working principles of both CST and its control system were introduced. Based on AMESim software, simulation model that includes motor model, CST model, scraper conveyor model, two levels negative feedback PID closed-loop control system model of rotational speed and pressure were established. Two kinds of start working conditions of the scraper conveyor were simulated, including normal soft start condition and load mutation condition during smooth running stage. The simulation results indicate that the PID modified electro-hydraulic servo closed-loop control system can satisfy requirements of soft start functions and dynamic performances of scraper conveyor.
