A Note on Parametric and Nonparametric Uncertainties in Control SystemsS. Boyd
Proceedings American Control Conference, 3:1847-1849, June 1986. It is shown that robust stability and robust performance questions for control systems with nonparametric uncertainties can be turned into those with a particularly simple parametric description. It is pointed out that there exist Routh-like procedures which determin whether a system containing uncertain subsystems is robustly stable (or robustly meets performance requirements). |
