A novel Multi-Receiver Vector Tracking (MRVT) architecture for the joint tracking of multiple GPS receivers to determine the reference position and attitude of a rigid body is presented. The reduction in overall search space, from the state variables of each individual receiver to a single reference position on the rigid body and the attitude of the rigid body, offers increased information redu...

This paper presents the design and simulation of a typical Ka band satellite beacon receiver for propagation experimentation. Using satellite beacon signal as a reference signal in satellite wave propagation study, is one of the most important methods. Satellite beacons are frequently available for pointing large antennas, but such signals can be used for measuring the effect of natural phenome...

The photovoltaic (PV) generator exhibits a nonlinear – characteristic and its maximum power (MP) point varies with solar insolation. In this paper, a feedforward MP-point tracking scheme is developed for the coupled-inductor interleaved-boost-converter-fed PV system using a fuzzy controller. The proposed converter has lower switch current stress and improved efficiency over the noncoupled conve...

Tracking of a reference signal (assumed bounded with essentially bounded derivative) is considered in the context of a class Σρ of multi-input, multi-output dynamical systems, modelled by functional differential equations, affine in the control and satisfying the following structural assumptions: (i) arbitrary – but known – relative degree ρ ≥ 1, (ii) the “high-frequency gain” is sign definite ...

This paper presents design and implementation of three new Infrared Counter-Countermeasure (IRCCM) efficient methods using Neural Network (NN), Fuzzy System (FS), and Kalman Filter (KF). The proposed algorithms estimate tracking error or correction signal when jamming occurs. An experimental test setup is designed and implemented for performance evaluation of the proposed methods. The methods v...

A control strategy that determines piecewise-constant control signals for the tracking problem of predator-prey systems is proposed, since this type of signal is an idealized model of management policies adopted by environmental agencies. The reference trajectories are chosen as to restore the original dynamics of a disturbed system. Assuming that the system model is completely known, it is sho...

in this paper, we examine target detection in the surveillance channels of fm-based passive bistatic radars (fbpbrs) in the presence of interference signals in the reference channels of these systems. to do so, we propose a new signal conditioning algorithm to remove interference signals form reference channel. simulation results show that the proposed signal conditioning algorithm outperform t...

A direct adaptive nonlinear tracking control framework for multivariable nonlinear uncertain systems with actuator amplitude and rate saturation constraints is developed. To guarantee asymptotic stability of the closed-loop tracking error dynamics in the face of amplitude and rate saturation constraints, the adaptive control signal to a given reference (governor or supervisor) system is modifie...

In general, we would like to investigate the steady-state performance of a feedback system to disturbances and/or reference inputs that are not only constants, but can be expressed as arbitrary polynomials in time. Assuming that the system under consideration is stable, we classify such systems into system types depending to the polynomial degree for which the tracking error is constant. System...
