This paper is concerned with the Hinfin control problem for linear continuous-time systems in mixed frequencies ranges. A state feedback controller is designed such that the resulting closed-loop system is asymptotically stable and satisfies entire frequency and finite frequency Hinfin performance respectively. Then a sufficient condition for the existence of the controller is derived in terms of...
This paper studies the problem of reliable Hinfin state feedback controller design for linear continuous-time systems. Actuator partial failures and actuator lock-in-place failures are simultaneously considered, and the signals in the case of certain actuators being locked in place are treated as zero-frequency disturbances, which gives an exact description for the lock-in- place failures. Based on...
The paper studies the problem of simultaneous design of fault tolerant controller and fault detector for a class of linear continuous-time systems with bounded disturbances and nonzero external constant inputs. A dynamic output feedback controller and a fault detector are designed simultaneously, where the output feedback controller stabilizes the closed-loop system for both normal and faulty cases...
The paper studies the problem of simultaneous design of reliable filter and fault detector for a class of linear continuous-time systems with bounded disturbances and nonzero constant reference inputs. An Hinfin filter and two detection weighting matrices are designed simultaneously. The filter is designed for both fault free and faulty cases, and by manipulating the steady-state values of the filter...
This paper studies the problem of non-fragile H∞ filter design for linear continuous-time systems. The filter to be designed is assumed to be with additive gain variations, which are due to the finite word length (FWL) effects when the filter is implemented. A notion of structured vertex separator is proposed to approach the problem, and exploited to develop sufficient conditions for the non-fragile...
