This project contains the Scilab source file for the simulation of a control loop with a boost converter. Contrary to many other approaches, the voltage output is directly used as a control variable. This results in a non-minimum phase system. The problems arising with this system property are circumvented using a parallel compensator. The intention of this project is to supplement the following conference paper:
Klaus Röbenack, Stafan Palis:
On the Control of Non-Minimum Phase Systems Using a Parallel Compensator.
International Conference on System Theory, Control and Computing (ICSTCC),
October 9-11, 2019, Sinaia, Romania
To carry out the simulation you need to install the follwoing open source software for numerical computation:
The src directory contains the Scilab source file:

The numerical simulation combined with the visualisation generates the following graphics showing the trajectories of the controlled system:
