This paper describes the black-box system identification and iterative learning control algorithm which apply to a quadcopter. At first, two feedback control loops from angles and angular velocities are implemented to stabilize the system, then the experimental data and the models of roll and pitch are identified via a black-box routine. For more accuracy of angles measurement, the complementary filter is used to fuse the data of the inertial measurement unit (IMU). An iterative learning control (ILC) method is then applied to the closed loop system with the aim of following trajectories of the roll and the pitch angles. The designed controller was first applied to the roll and pitch model separately and then applied to both angles simultaneously. The experimental result is presented and discussed.

Humans have two distinct features with compared to any other living being;unique physical nature and emotions / feelings. Anybody who studies on humans or trying to construct human like machines should consider these two vital facts. When robots are interacting with humans and other objects, they certainly have a safe distance between them and the object. But how can this distance be optimized when interacting with humans? Will there be any advantages over achieving this? Will it help to improve the condition of robots? Can it be a mere constant distance? How will the humans react? In order to 'humanize' robots, they (robots) should also have certain understating of such emotions that we, humans have. In this research project, authors are trying to 'teach' one such human understanding, commonly known as 'personal space' to autonomous mobile robots. ©ISAROB 2007.

37th AIAA/ASME/ASCE/AHS/ASC Structure, Structural Dynamics and Materials Conference, 1996

A novel learning scheme for training neural networks is proposed. The trained network is then used for function approximation during the numerical optimization process. The learning scheme trains the network with data of varying complexity, including data that has only zeroth order information and when the data includes first order information (gradients of responses with respect to the design parameters) it uses the combined information (response values and its gradients) for a better approximation. The learning scheme and its function approximation capability for design optimization arc demonstrated on two realistic examples. © 1996, American Institute of Aeronautics and Astronautics, Inc.

Work domain analysis is an approach that is moving from research to practical usage. Being highly analytical and time-intensive in its early stages, clients will search for early indications that the analysis is on track and relevant. This paper presents one approach for validating a work domain analysis by mapping the action patterns of operators against the work domain space developed by the analysis. This approach provides some validation the analysis, shows the use of the work domain over time in three dimensions, and provides a substantial link between the work analysis approach and traditional task-based approaches.

A finite element model of piezoelectric fiber transducers bonded to an aluminum plate is used to study planar guided waves inspection of a plate. It has been shown that a linear combination of in-plane and out of plane strains matches the transducer obtained voltage better than it does displacements. A combination of infinite elements and viscous surface tractions were employed to minimize unwanted boundary reflections to enable study of sensor sensitivity to small defects. Finally, design of a piecewise sensing element has led to successfully defining the location of a crack that is only 1.5% the length of the transducer.
