An Integrated Fuzzy Guidance (IFG) law for a surface to air homing missile is introduced. The introduced approach is a modification of the well-known Proportional Navigation Guidance (PNG) law. The IFG law enables the missile to approach a high maneuvering target while trying to minimize control effort as well as miss distance in a two-stage flight. In the first stage, while the missile is far ...

Time-growing navigation error due to inevitable measurement errors in the MEMS-grade inertial sensor is one of the main challenges in low-cost inertial navigation systems (INSs). This paper aims to develop AHRS/GPS/DR integrated navigation algorithm for long-range autonomous underwater vehicle (AUV). Proper performance in deals with long-term GPS outage is the main advantage of the proposed low...

Obviously navigation is one of the most complicated issues in mobile robots. Intelligent algorithms are often used for error handling in robot navigation. This Paper deals with the problem of Inertial Measurement Unit (IMU) error handling by using Extended Kalman Filter (EKF) as an Expert Algorithms. Our focus is put on the field of mobile robot navigation in the 2D environments. The main chall...

The growing demand for applications in Precision Agriculture has been proportional to the emergent interest in automatic guidance of agricultural machines. The difficult, and at the same time strenuous, task of driving a harvester during the prolonged working days of the harvesting season justifies the special attention paid to this technology. The development of Global Navigation Satellite Sys...

∗ Both authors are visiting professors at Macedonian Military Academy, and have significant contribution in teaching/research activities in the field of intelligent missile systems Abstract. We have developed a simulation model of homing-guided anti-aircraft or surface-to air (SA) missiles SAM, suitable for research, development and testing of different guidance and control laws, obtained from ...

This paper deals with the control of lighter-than-air vehicles, more specifically the design of an integrated guidance, navigation and control (GNC) scheme that is capable of navigating an airship through a series of constant-altitude, planar waypoints. Two guidance schemes are introduced, a track-specific guidance law and a proportional navigation guidance law, that provide the required signal...

Two major simultaneous attack strategies have been introduced, as one of cooperative attack of multiple missiles. One strategy is an undesignated time attack, in which the missiles communicate among themselves to synchronize the arrival times by reducing the mutual differences of times-to-go of multiple missiles during the homing. The other is a designated time attack, in which a common impact ...

This paper suggests to replace PIs and PIDs, which play a key role in control engineering, by intelligent Proportional-Derivative feedback loops, or iPDs, are derived from model-free control. standpoint is enhanced laboratory experiment.

​During the recent years, the need arises for indoor navigation systems for guidance of a client in natural hazards and fire, due to the fact that human settlements have been complicating. This research paper aims to design and implement a visual indoor navigation web application. The designed system processes CityGML data model automatically and then, extracts semantic, topologic and geometric...
