"Smart Materials Systems to Mitigate Some Vibration and Shock Problems in Aerospace Systems"

The lightweight structural design has become essential in aerospace industry to reduce aircraft/spacecraft weight, to improve performances, and to reduce fuel consumption. However, lightweight structures are often accompanied by more serious vibration problems. Often these excessive vibration problem can be mitigated by employing smart material systems. This talk focuses on smart material systems that pertain to vibration monitoring and suppression. Firstly, the full-field real-time measurement of vibrations of a structure based on fiber-optic technology will be introduced. Optical fibers are the preferred sensor material for vibration monitoring because optical fibers are small and lightweight, consume less power, and are immune to electromagnetic interference. Real-time shape estimation of several composite structures including a wind turbine blade model was accomplished at SSS KAIST using strain data gathered by the arrayed fiber Bragg grating (FBG) sensors. Secondly, a new type of shock and vibration isolator using SMA materials will be introduced. A novel frequency tuning method of the isolator is proposed to achieve both shock attenuation performance and avoidance of the vibration amplification. The last topic is about micro-vibration problems in satellite. Why the microvibration is important is explained, and their effects on optical payloads are systematically estimated. Some vibration isolator designs and their performances are presented.

"Unmanned Vehicle: Guidance, Control, and its Potentialities"

Unmanned vehicles, especially Unmanned Aerial Vehicle (UAV) has seen unprecedented growth during the last decade, with even more expectations for future utilization in a very wide spectrum of possible applications such as inspection in inconvenient or dangerous area. While benefiting from the growth, new challenges arises as improvement on structural design. We have developed a quad tilt wing UAV like a multicopter to widen application range of an unmanned system. The UAV is capable of vertical takeoff and landing like a helicopter and level flight like an airplane during a mission. On the other hand, Unmanned Ground Vehicle (UGV) has been actively used for exploration of unknown environment, disaster monitoring, and surveillance. The vehicle sometimes requires simultaneous localization and mapping in non-GPS environment, irregular ground traveling, and collision avoidance for an exploration. It is important for the vehicles to realize real time control, to have robustness against disturbances and to consider fault tolerance. In this talk, recent research work will be highlighted in this area, focusing on guidance and control of nonlinear dynamics of the vehicles. Furthermore, this talk will present work on formation flying of UAVs and cooperation of UAV-UGV for constructing efficiency system. Our work will also be presented with successful demonstration.

"Approach to Detection and Tracking of Infrared Small Target Based on Reinforcement Learning and Discriminative Classification with Gaussian Mixture Model"

In this talk, some research results are presented about detection and tracking of infrared small target, which may exhibit one side of the speakers recent achievements in the Lab of Pattern Recognition and Intelligent Systems, Beihang University, Beijing, China. At first, an adaptive detection method of infrared small target is introduced based on target-background separation via robust principal component analysis. Then an approach for moving small target detection is presented under a pipeline framework with an optimization strategy based on reinforcement learning in view of background clutter and target size variation with time. Finally an infrared small target tracking method is addressed by means of discriminative classification with Gaussian mixture model of compressive appearance distribution. Frankly speaking, it is a challenge topic to implement high performance detection and tracking of infrared small target, we hope to exchange some beneficial research progress and consult with our colleagues and experts so as to make more efforts to achieve great success in some relevant research fields.
