摘要
针对超级压光机速度控制中采用常规算法很难解决压光机速度跌落的这一控制难点,对传统解决办法进行了改进,提出了变速积分PID控制算法。在改进的控制算法中,积分增量在整个控制过程中是变化的,系统偏差大时积分作用减弱甚至全无,而在偏差小时则加强。仿真结果表明,变速积分PID能较好地解决超级压光机速度跌落问题,使系统控制效果得到很好的改善。
Supercalender velocity drop always is a control difficulty of electricity control technology, and it is difficult to solve the problem of velocity drop by common arithmetic. On account of this practice problem, a new arithmetic, variational velocity integral PID arithmetic, is proposed, as the improvement of the traditional solution method. In the improved arithmetic of PID, integral increment is changeable in the whole control process. When system error is very huge, integral effect will be weakened even disappeared, and when the error is small, the effect will be enhanced. Overshoot caused by overlarge integral coefficient is solved completely, even saturation state or static difference due to little integral coefficient. Simulation results show that variational velocity integral PID can solve supercalender velocity drop better and improve system control efficiency.
