Hybrid Robust H2/H∞ Fault-Tolerant Control with Random Delay NCS by Jun Wang, Miaomiao Ling

“…The problem of less conservatism of robust generalized H2/H∞ hybrid fault-tolerant control is studied. Firstly, a closed-loop fault model of the system with random delay parameters was established according to the Bernoulli 0-1 distribution; all possible prior faults are divided into a few intervals according to certain rules, and then an interval fault-tolerant controller is designed off-line according to the prior faults of each interval. …”

Robust and Arbitrary Pole Placement using Static Output Feedback by El Faiz Samira, Guerbaoui Mohammed, Ed-Dahhak Abdelali, Lachhab Abdeslam

“…This paper presents the output feedback pole assignment methods that attempt to achieve a robust solution where the arbitrary choose of the poles to be assigned are as insensitive as possible to perturbations in the closed loop system. The robust and arbitrary pole placement problem is formulated as a nonlinear and non-convex programming problem with a nonlinear constraint on matrix functions as well as a linear constraint. …”
