| 摘 要： | 针对镁合金熔炉的纯滞后特性,采用smith预估器对系统进行补偿.根据镁合金熔炉的结构和特性,建立了以PID和smith预估器为核心的温度控制系统模型;然后设计了硬件系统和软件控制流程;再通过simulink仿真比较了普通PID控制和simth预估控制模式.结果表明,smith预估控制系统可以消除系统的静态误差,减小超调,缩短调节时间,提高控制精度,使得系统运行稳定,性能明显优于普通的PID控制系统.

| Abstract: | Aiming at the problem of large delay in temperature control of magnesium alloy furnace,a method of Smith predicting control was used.According to the magnesium alloy furnace's characteristic and structure,the temperature control model was built based on the PID and smith predictor in detail,and its hardware system and flow chart were presented.Comparison of Smith predictor control system and PID control system demonstrated that the former can eliminate the static error,reduce overshoot,shorten regulating ti... |
