A selective state observer capable of asymptotically tracking any arbitrarily chosen subset of the state vector of linear time-invariant multivariable dynamic systems is introduced. The dynamics of the observer are derived from a model of the subset to be estimated. It is shown that the only condition for the asymptotic tracking of the subset is that the… (More)

A common requirement implicit in current methods for the design of robust state estimators and robust fault detection filters is that the first Markov matrix must be non-zero, and indeed, full rank. We relax both of these restrictions in this paper to allow the applicability to a wider range of systems. The extended results are then applied to an aircraft… (More)

A simple and computationally efficient decentralised control design method is introduced for load-frequency control (LFC) in interconnected power systems. The method is based on the use of a reduced-order observer and a proportional-plus-integral controller in each area of the power system, and ensures zero static change in area-frequency and tie-line… (More)

Abstract: This paper considers a class of uncertain, nonlinear differential state delayed control systems and presents a reduced-order observer design procedure to asymptotically estimate any vector state functionals. The method proposed involves decomposition of the delayed portion of the system into two parts: a matched and mismatched part. Provided that… (More)

-This paper presents a robust approach to real time detection of faults in the load-frequency control loop of interconnected power systems. The detection of faults takes place under different operating conditions, in the presence of modeling uncertainties, unknown changes in the load demand and other external disturbances, such as plant and sensor noise.… (More)

A method is presented for the systematic design of stabilising decentralised controllers for large-scale interconnected dynamical systems. The design method is based on (i) decentralised implementation of global controllers obtained by using existing global controller design methods, (ii) model reduction of dynamical systems, and (iii) modelling of the… (More)

A new technique for fault diagnosis and estimation of unknown inputs in a class of nonlinear systems is presented in this paper. The novelty of the approach is based on utilization of a network of two interconnected sliding mode observers, the first is used for fault diagnosis and the second is used for estimation of unknown inputs. The two observers… (More)

This paper presents a modified maximum power point tracker (MPPT) for a standalone PV system. In this research a Particle Swarm Optimization (PSO)-based method is re-initialised by a variable step size (VSS) incremental conductance (IncCond) MPPT. The main motivation in this research is to eliminate the output ripple, and also to shorten the tracking time… (More)

This paper presents a new technique for fault diagnosis and estimation of unknown inputs in a class of nonlinear systems. The novelty of the approach is governed by the use of two interconnected sliding mode observers. The first of the two observers is used for fault diagnosis and the second is used for the reconstruction of unknown inputs. The two… (More)

A new design method for a distributed power system stabiliser for interconnected power systems is introduced in this paper. The stabiliser is of a low order, dynamic and robust. To generate the required local control signals, each local stabiliser requires information about either the rotor speed or the load angle of the other subsystems. A simple MATLAB… (More)
