Abstract
Achieving fault tolerance in process control usually involves supervision and reconfiguration. On the other hand, common robust control approaches achieve a common performance level for a family of plants, which can be unsatisfactory in the nominal case if faulty conditions are not taken into account. This paper discusses the problem of guaranteeing both a nominal performance and a degraded second-class control performance under actuators' permanent faults, by using a time invariant controller. LMI, BMI and other possible solutions are investigated in a multivariable state feedback control framework. Two examples from the literature (reactor and jet bank angle control) illustrate the procedure.
