Abstract EN
This paper deals with the robust performance problem of a linear time-invariant control system in the presence of robust controller uncertainty.
Assuming that plant uncertainty is modeled as an additive perturbation, a geometrical approach is followed in order to find a necessary and sufficient condition for robust performance in the form of a bound on the magnitude of controller uncertainty.
This frequency domain bound is derived by converting the problem into an optimization problem, whose solution is shown to be more time-efficient than a conventional structured singular value calculation.
The bound on controller uncertainty can be used in controller order reduction and implementation problems.
