摘要
由于传统的带式输送机驱动系统存在着结构相对复杂、占用空间大、故障率高及维护成本高等缺点,设计了基于滑模观测器算法的煤矿带式输送机用永磁同步电动机控制系统,根据永磁同步电动机两相静止坐标系下的数学模型,在MATLAB/Simulink中搭建了仿真模型。仿真分析结果表明,该控制系统调速性能好、转速响应快、波动小,能够准确跟踪转子位置,转速估计值精度高,控制系统设计合理。
Since the traditional drive system of the belt conveyor has the disadvantages such as relatively complex structure,large space occupation,high failure ratio and high maintenance cost,the control system for the permanent magnetic synchronous motor(PMSM)of the mine-used belt conveyor was designed based on sliding mode observer(SMO)algorithm.According to the PMSM mathematical model in two-phase static coordinate system,the simulation model was built in MATLAB/Simulink.The simulation results showed the control system was characterized by excellent speed control performance,rapid speed response and small fluctuation,accurately traced the position of the rotor,and was of high accuracy in speed valuation and reasonable design.
