ABSTRACT:
A closed-loop control system having two feedback paths 106, 108. A first feedback path contains an expected system output value generated by a system model 102. The second feedback path provides insensitivity to noise by heavily filtering the error between the model output 104 and the actual measured system output 74. Because of the delay associated with the filtering operation, the dual feedback paths result in an initial fast (but approximated) system response, followed by a delayed correction to that response.
