Control system auto-tuning

摘要

A control system includes a controller. The controller repeatedly excites a control loop characterized by parameters having randomly selected values for each excitation and scores a response of the control loop to each excitation relative to a target signal until the scores no longer achieve a value less than a minimum of the scores for a predefined number of excitations occurring after the excitation yielding the minimum of the scores to auto-tune the control system.

1. A control system comprising:
at least one processor configured to
perform a plurality of trials that each result in a score until the scores no longer achieve a value less than a minimum of the scores for a predefined number of trials occurring after the trial yielding the minimum of the scores, each of the trials including
(i) providing a demand signal to a control loop having parameters,(ii) comparing a target signal to a response to the demand signal,(iii) generating a score based on the comparison, and(iv) randomly adjusting values of the parameters, andoutput parameter values that yielded the minimum of the scores to auto-tune the control system.
