数字PID控制中饱和问题的研究

An Investigation on Saturation Problem in Digital PID Control

研究了数字PID算法中的饱和效应,提出克服饱和现象的各种算法。还通过仿真,研究了比例饱和、积分饱和、微分饱和三种情况下各种算法的性能。最后指出微分项带滤波的PID算法具有良好的抗饱和能力。

The saturation effect in digital PID algorithm is investigated and various algorithms overcoming saturation phenomenon are stated. By using simulation, the features of various algorithms under three kinds of saturations, i.e.ratio saturation, integral saturation and differential saturation are studied. Theauthor states that the PID algorithm using differential item with filtering has excellent saturation-proof ability.
