Pilot Demonstration Based Reinforcement Learning With Application To Low Speed Airship Control, Onur Daskiran

Mechanical and Aerospace Engineering Dissertations - Archive

Designing control systems for airship has unique challenges as compared to conventional aircraft. Highly nonlinear dynamics, different mass/inertia relations, vast uncertainties in the model parameters and underactuation are the main reasons behind this. Airship dynamics is greatly influenced by the variations in the environmental (e.g.,room temperature) and internal (e.g., helium distribution in envelope) factors that can completely change the response characteristics of the blimp and make it infeasible for a model-based controller to perform. On the other hand, a skilled RC pilot can operate the manual flight easily under these conditions. This makes LfD (learning from demonstration) and RL (reinforcement …

Non-Invasive Measurement Of The Internal Temperature Of Heat-Generating Bodies, Dean Raymond Anthony Dec 2016

Non-Invasive Measurement Of The Internal Temperature Of Heat-Generating Bodies, Dean Raymond Anthony

Mechanical and Aerospace Engineering Theses - Archive

While the surface temperature of a heat-generating solid body can be measured using a variety of methods, there is a scarcity of techniques that exist for non-invasively measuring the temperature inside the solid body. Internal temperature measurement is very desirable as mere measurement of surface temperature gives no indication of the internal temperature. The highest temperature, usually located at the core of the body, dictates system performance and safety. For example, Li-ion cells provide good energy storage and conversion characteristics, but unfortunately suffer from safety problems related to overheating due to insufficient heat removal during operation. The following thesis presents …
