CLOSED-LOOP APPARATUSES FOR NON LINEAR SYSTEM IDENTIFICATION VIA OPTIMAL CONTROL

摘要

A closed-loop method for optimally identifying a system structure by determinig the relationship between control settings and system response for at least one function of the system (130), within which at least one system component produces a change in the form of a measurable system response, wherein the method includes the steps of: operating the system through one or more control settings to produce a system response; collecting the system response data; inverting the system response data with a globally searching inversion algrithm (145) and determining the distribution of inverted system structures consistent therewith; analyzing the distribution of inverted system structures with a learning algorithm (135) and determining one or more new control settings that will reduce the distribution of inverted system structures; and interactively repeating the steps of the method using the newest control settings, until the distribution of inverted system structures cannot be further reduced. An apparatus incorporating the inventive method is also disclosed, as well as methods and apparatuses for closed loop system control, and methods and apparatuses by which the system identification and control methods and apparatuses are operated in tandem for the determination of optimal control settings to give the best system identification possible.
