The method comprises the steps of selecting random number dimensionality, selecting cycle number and selecting controller result. Mainly aiming at a PID controller parameter selection problem, the invention designs and develops the parameter selection method based on a random algorithm. The method comprises the steps of firstly determining the quantity of parameters to be selected, and generating corresponding quantity of parameters through a random algorithm; then applying the randomly produced parameters to a controller, and performing circulating experiment; finally, judging control results according to a selected judgment standard, and selecting a range meeting the judgment standard for each parameter.

Description

technical field [0001] The invention belongs to the technical field of controllers. Background technique [0002] The rationality of PID controller parameter selection is the prerequisite and basis for determining whether the controller has good working performance. Reasonable PID parameters will improve the calculation speed and control performance of the controller. However, the current domestic PID parameter selection technology is generally still in the time-consuming and laborious manual identification stage, and the controller parameter selection mainly has the following problems: [0003] 1. When the same PID controller controls different controlled objects, the controller parameters also need to be reselected, which leads to repeated workload and low work efficiency. [0004] 2. The traditional manual selection of PID parameters requires repeated simulation experiments, continuous recording of control results, and repeated comparisons to determine. This method has a...
