NLS: A System Identification Package for Transient Signals. Description and User's Manual

摘要

NLS is a system identification package designed specifically for determining difference-equation models for systems whose inputs and outputs are transients. In its present from the code is available only for a VAX 11/780 using the VMS operating system, but transporting it to a different system should not be difficult. I emphasize that this document is a preliminary edition describing a preliminary version of NLS. The purpose of this manual is to show potential users how to run NLS intelligently; it is not intended to be a treatise on system identification. We describe the particular methods used by NLS, but the user must be able to decide for himself if these methods apply to his particular problems. Much of the manual is devoted to explaining the various optimization methods employed by NLS so that the user will be able to select the parameters which control their behavior.
