While autonomous landing of unmanned aerial vehicles (UAVs) requires accurate position estimation, the standard inertial navigation unit (INU, the inertial measurement unit with a global positioning system (GPS)) provides relatively poor accuracy in

A fully tuned Growing Radial Basis Function (GRBF) neural network controller for the control of robot manipulators is proposed. In addition to the weights, the centers and the standard variations are adapted online. Furthermore, we present an algorit

In this paper, we present a neural network algorithm to estimate the I-V curve of a photovoltaic (PV) module under non-uniform temperature and shading distributions. We first present a novel photovoltaic simulation model which includes the interactio

Classical Radial Basis Function (RBF) neural network controller designs typically fix the number of basis functions and tune only the weights. In this paper we present a backstepping neural network controller algorithm in which all RBF parameters, in

In this paper, we introduce and describe a new type of Joint Time-Frequency Analysis (JTFA), which we call the Windowed Laplace Transform (WLT) method. In addition to general signal processing applications, this new method can be used to extend Nyqui

Using non-navigational (e.g. imagers, scientific) sensor information in control loops is a difficult problem to which no general solution exists. Whether the task can be successfully achieved in a particular case depends highly on problem specifics,
