摘　　要：针对粗甘油精炼过程中甘油蒸馏釜温度控制系统具有惯性大、滞后严重的特点,设计了一种采用积分分离PID算法的釜温控制系统。使用MATLAB软件自带的Simulink仿真环境,构建釜温控制系统模型,并对其进行仿真,结果表明:该设计增强了系统的稳定性,提高了控制精度,减小了超调量。According to the characteristics of larger inertia and serious hysteresis of the glycerine distillation temperature control system in the process of crude glycerol refning,a kettle temperature control system based on integral separation PID algorithm is designed.UsingSimulink environmentwhich built in MATLAB software,the model of kettle temperature control system is constructed and simulated,the results show that the design enhancesthe stability of the system,improves the control accuracy and reduces overshoot.
