Fuzzy logic in autonomous orbital operations

Fuzzy logic in autonomous orbital operations

Fuzzy log& can be used advantageously in autonomous orbital operations that require the capability of handling imprecise measurements from sensors. Several applications are under way at the Software Technology Laboratory, NASA / Johnson Space Center to investigate fuzzy logic approaches and develop guidance and control algorithms for autonomous orbital operations. Translational as well as rotat...

Operations and Methods in Fuzzy Logic Systems

This paper looks to introduce the reader to the idea of a fuzzy logic system and how this type of system differs from traditional propositional logic systems by way of summarizing the foundational ideas presented in Hájek’s Metamathematics of Fuzzy Logic. Because a fuzzy system has different laws from a standard propositional one, propositional logic operations such as conjunction and implicati...

Fuzzy Logic Control in Autonomous Robotics:

Autonomous robot systems require complex control systems. Fuzzy Logic, a mathematical system developed by Professor Lotfi Zadeh, helps to reduce the complexity of modeling nonlinear problems. In the 1990s, Motorola developed the MC68HC12 microcontroller with native Fuzzy Logic instructions. This research determined the effectiveness of the MC68HC12’s Fuzzy Logic instructions for robotic control...

Applying Fuzzy Logic to Operations Management Research

Using Fuzzy Logic for Autonomous Navigation

 Successful navigation for unmanned autonomous vehicles (UAVs) depends on the ability of the navigation algorithm to fuse data from disparate sensor systems into a single direction command in real time, taking into account the various and sometimes contradictory goals of the UAV. In this paper, a fuzzybased method of sensor data analysis, fusion, and navigation is investigated. The results of ...
