The fixed-order H∞ FDI filter design is characterized in terms of definite LMIs with no equality constraint, which are done recen...

This paper presents a framework for examining joint optimal channel-capacity allocation and controller design for networked control systems using store-and-forward networks in a discrete-time linear time-invariant setting. The resultant framework provides a synthesis procedure for designing distributed linear control laws for capacity-constrained networks taking the allocation of the capacity w...

Spectrum is presently one of the most valuable goods worldwide as the demand is permanently increasing and it can be traded only locally. Since the United States Federal Communications Commission (FCC) has opened the spectrum from 3.1GHz to 10.6GHz, that is, a bandwidth of 7.5GHz, for unlicensed use with up to −41.25dBm/MHz EIRP, numerous applications in communications and sensor areas are show...

A new method for fault detection and isolation (FDI) in stochastic linear time varying (LTV) systems is proposed in this paper. It allows to completely isolate any number of faults regardless of the number of output sensors, thanks to an appropriate assumption on the fault profiles and to some persistent excitation condition. In contrast, most existing methods enabling complete fault isolation ...

In this paper we present three new schemes for sensor and actuator fault diagnosis for linear time-invariant systems: multirate parity-space techniques, multirate observers, and multirate detection filters. We show that these approaches offer distinct advantages over conventional fault diagnosis schemes in terms of ease of failure detection, the speed and the class of systems for which detectio...

The applicability of employing a parameter-dependent control to a nuclear pressurized water reactor is investigated and is compared to that of using an H1 control. A linear time-invariant controller cannot maintain performance over the entire operating range. The parameterdependent synthesis technique produces a controller which achieves speci ed performance against the worst-case time variatio...

Based on the bounds due to Doyle and Boyd, we present simple upper and lower bounds for the `-norm of the `tail' of the impulse response of nite-dimensional discrete-time linear time-invariant systems. Using these bounds, we may in turn compute the `1-gain of these systems to any desired accuracy. By combining these bounds with results due to Khammash and Pearson, we derive upper and lower boun...

This paper considers state estimation for multiple plants over a shared communication network. Each linear time-invariant plant transmits information through the common network according to either a timetriggered or an event-triggered rule. For an event-triggered algorithm with CSMA (carrier sense multiple access), each plant is assumed to access the network based on a priority mechanism. For a...

Abstract: By using the concept of parameter varying (C,A)-invariant subspace and parameter varying unobservability subspace, this paper investigates the problem of fault detection and isolation in linear parameter varying (LPV) systems. The so called detection filters approach, formulated as the fundamental problem of residual generation (FPRG) for linear time invariant (LTI) systems is extende...

Observers for distributed fault detection of interconnected second-order linear time invariant systems is studied. Particularly, networked systems under consensus protocols are considered and it is proved that for these systems one can construct a bank of so-called unknown input observers, and use their output to detect and isolate possible faults in the network. The application of this family ...
