A piecewise linear (PWL) model can be used to simplify a problem, by replacing a complex model with on that is made up of simpler (linear) pieces. For example, the IV curve for a diode is Id = Is( exp(Vd/n*Vt) - 1). Quite messy. We can instead represent the curve by two pieces. One where the current is zero from 0V, to arround 0.5-0.7V. From here, we approximate the exponential curve with a linear relationship. This linear region is typically fixed on a point on the exponential curve known as the operating point, Q. See link.

The form of the piecewise functions can be arbitrarily complex, but higher degrees of specification require considerably more user input.


What is meant by Piecewise linear interpolation?

Interpolation in general is a way to determine intermediate values from a set of coordinates. Linear interpolation would be to fit a single linear function to the entire set of coordinates. Piecewise linear interpolation would then be to determine intermediate values from the set of coordinates by fitting linear functions between each set of coordinates. Connect-the-dots so to speak.

Definition of piecewise linear chaotic map?

the piecewise linear chaotic map is defined as follows: xi+1=Fpi(xi)= xi/pi if 0<=xi<pi (xi-pi)/(0.5-pi) if pi<=xi<0.5 Fp(1-xi) if xi>=0.5 where 0<=xi<1 and the control parameter 0<pi<0.5
