This paper presents a backstepping control design for small scale helicopters. The objective is for the helicopter to autonomously track predefined position and yaw trajectories. The position reference trajectories are arbitrary, possibly aggressive, with some constraints in their higher order time derivatives. The main idea of the algorithm is to control the direction and magnitude of the thrust...
This paper presents a novel task allocation methodology based on supervisory control theory applicable to cooperative robot teams. A team of heterogeneous robots with different sensory capabilities is considered. The overall team's mission is decomposed into multiple tasks which are assigned to one or more robots. An evaluation function is utilized to provide optimal task allocation. The proposed...
This paper presents a practical and simple approach to the design of autonomous flight control of miniature helicopters. It considers a standard easily tunable PID control as the starting step of the design. Then, robust loop-shaping techniques are applied to derive a controller with optimal properties with respect to robustness, noise sensitivity, and bandwidth. Comprehensive analysis and simulation...
Unmanned ground vehicles (UGVs) have strict payload limitations, limited free space affecting power supply availability (number of batteries, size and volume) that impact onboard available energy resulting in limited endurance and operational range. This limitation is exacerbated by the addition of extra sensors and other related equipment needed for diverse applications. The ATRV-Jr UGV is considered...
Design, implementation and experimental validation of a MATLAB based autonomous robot control framework is presented, supported by, and integrated into a distributed field robot architecture known as distributed-SFX. The MATLAB based framework is composed of multi sensor fuzzy logic robot controllers that utilize laser, GPS and odometer data, fusing such sensor data and filtering out noise, to improve...
