Fits linear and polynomial models to data using linear least squares and approximates nonlinear models through linearization. - tamaskis/lsqcurvefit_approx-MATLAB ...

To model the non linear IV characteristics of LED, some advanced modeling techniques viz. Piecewise Linear Approximation and Maclaurin series expansion based modeling have been taken up in this paper.

The former is efficient for analyzing control systems with sample-and-hold while triangular functions established their superiority in obtaining piecewise linear solution of various control problems.

This is where model approximation or reduction comes into play. The aim is to simplify a high-dimensional dynamic model while preserving, as far as possible, its behavior and main characteristics.
