Frequency Domain System Identification Toolbox
Tools for frequency domain model identification and validation
Highlights
- 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
Description
Identify the behavior of a robot arm with an estimate for 4 zeros and 6 poles.
The 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.
