New Features of P3$\delta$ Software. Insights and Demos

This paper presents the software entitled “Partial Pole Placement via Delay Action”, or “P3$\delta$” for short. P3$\delta$ is a Python software with a friendly user interface for the design of parametric stabilizing feedback laws with time-delays for dynamical systems. After recalling the theoretical foundation of the so-called “Partial Pole Placement” methodology we propose as well the main features of the current version of P3$\delta$. We illustrate its use in feedback stabilization of several control systems operating under time delays.
