چکیده

This note presents a method for the reduction of controller fragility. The method is based on the sensitivity of closed-loop poles to perturbations in the controller parameters. By means of a state space parameterization of the controller, the closed-loop pole sensitivity can be reduced. A controller fragility measure based on the closed-loop pole sensitivity is proposed. Conditions for the optimal state-space realization of the controller are presented, along with a numerical method for obtaining the solution.

Parametric H∞ loopshaping and weighted mixed sensitivity minimization

Generalized H 1 loopshaping is developed for a particular weighted mixed sensitivity minimization task. A free parameter is introduced to trade-oo minimizations of sensitivity and complementary sensitivity in the H 1 performance index. A quadratically convergent algorithm is derived for computing the optimal performance index and a state-space solution is obtained for suboptimal controllers. Th...
