A Modified Model-Free Adaptive Control Method for Large-Scale Morphing Unmanned Vehicles

An adaptive modified firefly algorithm to unit commitment problem for large-scale power systems

Unit commitment (UC) problem tries to schedule output power of generation units to meet the system demand for the next several hours at minimum cost. UC adds a time dimension to the economic dispatch problem with the additional choice of turning generators to be on or off.  In this paper, in order to improve both the exploitation and exploration abilities of the firefly algorithm (FA), a new mo...

A Queueing Model for Supervisory Control of Unmanned Autonomous Vehicles

Intelligent Control for Unmanned Vehicles

The NIST robot vehicle, a HMMWV with sensors and computer controlled actuators, detects and avoids obstacles while it drives off road at speeds up to 35 km/h. During tests the vehicle drives through the back fields of NIST detecting large obstacles up to 50 m away. Obstacles are sensed using a 30¡x60¡ field of view laser range scanner. The planner computes smooth, obstacle free paths that follo...

A Practical Desalinization Model for Large Scale Application

Salinity of soil and water is the most important agricultural hazard in arid and semi-aridregions. In saline soils, yield production directly influences by soluble salts in the root zone aswell as by shallow water table depth. The first step for reclamation of such soils is reducingsalinity to optimum level by leaching. The objective of this study was to develop a practicalmodel to estimate wat...

Nonlinear Model Predictive Control Technique for Unmanned Air Vehicles

A nonlinear model predictive control strategy is developed and subsequently specialized to autonomous aircraft that can be adequately modeled with a rigid 6-degrees-of-freedom representation. Whereas the general air vehicle dynamic equations are nonlinear and nonaffine in control, a closed-form solution for the optimal control input is enabledby expandingboth the output and control in a truncat...
