摘　　要：提出一种新的改进PID控制算法———连续变速积分控制算法。对其进行了仿真,与常规PID算法进行了比较,并将其应用于小型电加热炉的控制中。仿真及实际应用结果表明,该算法可提高控制质量,克服了常规PID算法容易造成超调与积分饱和的问题,且易于进行参数整定,特别适用于间歇生产过程及程序温度控制。The new improved PID algorithm-an algorithm of continues speed change integral and its application are presented. The new algorithm is compared with traditional PID algorithm through simulation, and its practical application - the temperature control of small electrical furnace for MFCC unit is introduced. Simulation and practical application show that comparing with PID algorithm, it has the features of ease tuning and good control quality. It overcomes the problems of overshoot and integral saturation in normal PID algorithm, especially suitable for use in intermittent process and the programmed temperature control.
