Abstract

The aim of this work is to study the reliable control design problem for parameter-dependent interconnected systems in the presence of actuator failures. Moreover, the control ensures H∞ performance in front of L2 perturbations. A more practical model of actuators or control channel failures than outage is adopted, considering partial achievement. The continuous H∞ control problem is solved via elementary manipulations on linear matrix inequalities and the resulting control systems are robustly stable against plant uncertainties and failures.
