· Design of optimized periodic excitation signals (multisine, binary, three-level)
· Identification of continuous-time or discrete-time systems with unknown fractional delay
· Model order selection
· Model validation, including simulation, calculation of residuals, and test of cost functions
· Calculation of confidence intervals of amplitude/phase and poles/zeros
· Model conversion to and from the Control System Toolbox and System Identification Toolbox objects
Frequency Domain System Identification Toolbox (FDIDENT) provides specialized
tools for identifying linear dynamic single-input/single-output (SISO) systems
from time responses or measurements of the system's frequency response.
Frequency domain methods support continuous-time modeling, which can be a
powerful and highly accurate complement to the more commonly used discrete-time
methods. The methods in the toolbox can be applied to problems such as the
modeling of electronic, mechanical, and acoustical systems.
The Frequency Domain System Identification Toolbox is built entirely in MATLAB and all functions are available from the MATLAB command line or through an interactive interface.
The current version of the Toolbox is Version 4.1r, June 19, 2019, tested for MATLAB 9.6 (2019a).
Backward compatibility is maintained also
with MATLAB 9.x, 8.x, 7.x, 6.x, and 5.3: R11.
Subscribers will receive a new passcode from the distributor when they upgrade their MATLAB. If you download a subscriber version, and have received no new passcode yet, please email us.
