本文指出PID增量算法在设定值跳变和手动自动切换时闭环控制系统易产生欠调现象 ,通过分析我们发现这种控制性能下降的情况是由于饱和问题所造成的 ,我们给出了一种改进PID增量算法以消除饱和问题的影响 ,实际工业应用效果证明了这种算法的有效性
This paper points out that the PID incremental algorithm is easy to produce under-tone in the closed-loop control system when the setpoint jump and manual automatic switchover. By analyzing, we find that this control performance degradation is caused by the saturation problem, we give a Improve the PID incremental algorithm to eliminate the impact of saturation problems, the actual industrial application proved the effectiveness of this algorithm
