Automatic generation control (AGC) of a power system provides power demand signals for power generators to control frequency and tie-line power flow due to the large load changes or other disturbances. Occurrence of large real power imbalance causes large frequency deviations from its nominal value which may be a threat to secure operation of power system. To avoid such situation, emergency con...

The importance of nutritional guidance grows as nutritional problems, such as obesity and type-2 diabetes, are becoming more common. Nutritional guidance is carried out by mapping the nutritional state of an individual using a food diary and by comparing the nutrition intake levels to the recommended reference values. Typically, the expert knowledge of a nutritionist is required to balance the ...

A guidance law, based on supervisory recurrent fuzzy neural network control (SRFNNC), is proposed for the autonomous underwater vehicle (AUV) guidance systems. This SRFNNC system is comprised of a recurrent fuzzy neural network (RFNN) controller and a supervisory controller. The RFNN controller is used to mimic an ideal controller and the supervisory controller is designed to compensate for the...

CONTROLLER USING FUZZY INFERENCE SYSTEMS by SWETHA PANDHITI (Under the Direction of Walter D. Potter) ABSTRACT The objective of this research is to design a controller for low-cost fixed-wing unmanned aerial vehicles (UAV‘s) using fuzzy rules and fuzzy inference systems. The control flow in the architecture design process is considered in four levels Guidance, Navigation, Control & Stability an...

An Optimal fuzzy logic guidance (OFLG) law for a surface to air homing missile is introduced. The introduced approach is based on the well-known proportional navigation guidance (PNG) law. Particle Swarm Optimization (PSO) is used to optimize the of the membership functions’ (MFs) parameters of the proposed design. The distribution of the MFs is obtained by minimizing a nonlinear constrained mu...

In fairly elementary terms this paper presents how the theory of preordered fuzzy sets, more precisely quantale-valued preorders on quantale-valued fuzzy sets, is established under the guidance of enriched category theory. Motivated by several key results from the theory of quantaloid-enriched categories, this paper develops all needed ingredients purely in order-theoretic languages for the rea...

This paper presents a new formulation of terminal guidance law which controls the impact attitude angle while minimising the miss distance. The formulation is based on the fuzzy logiccontrol approach. Unlike many prevalent designs, the proposed guidance law does not require linearisation of missile-target engagement model. Numerical simulation results demonstrate that the proposed guidance law ...

Direct volume haptics can provide both guidance and extra information during exploration of volumetric data. In this paper we present a novel approach to volume haptics enabling haptic exploration of tissue shape, borders and material properties in data despite low contrast and low signal to noise ratio, as is common in medical MRI data or low dose CT data. The method uses filtering based on im...
