How does it work?

Pisa is a toolbox for closed-loop stability analysis. It determines whether the impedance presented by the circuit has poles in the complex right half-plane to determine whether the circuit is stable.

The Pisa approach to stability consists of three steps:

  1. Determine the impedance presented by the circuit (see Closed-loop stability analysis)
  2. Project onto a basis for stable and unstable functions to determine stability.
  3. Estimate the location of the unstable poles when the circuit is unstable.

The details for each step are explained on their separate page.
