Stability region for a class of open-loop unstable linear systems: theory and application
A new method to calculate the stability region of scalar systems with one unstable pole subject to control limitations is derived and used to determine the conditions for a maximum stabilizer controller. The results are illustrated by means of two numerical examples and experiments on the real COMPASS-D tokamak.
