Adaptive Control for Nonlinear Mechanical Systems
非線形メカニカルシステムの適応制御

Koichi OSUKA
1986 Transactions of the Society of Instrument and Control Engineers  
In general, dynamic models of mechanical systems, such as manipulators, are highly nonlinear. This is the reason why control of such systems is difficult.  ...  In this paper, a model referenced adaptive control system (MRACS) for nonlinear mechanical systems is proposed.  ...  In general, dynamic models of mechanical systems, such as manipulators, are highly nonlinear.

Explainable software systems

Andreas Vogelsang
2019 it - Information Technology  
More specifically, we describe an architectural framework for designing self-explainable software systems, which is based on the MAPE-loop for self-adaptive systems.  ...  Afterward, we show that explainability is also important for tools that are used by engineers during the development of software systems.  ...  Adding such self-explainability capabilities, however, is difficult.  ...

Why can't we implement this SDM? [systems development methodology]

T. Roberts
1999 IEEE Software  
The real question becomes, "If you know what you need to do to implement an SDM, why are you not doing it?" WHY ARE IMPLEMENTATIONS SO DIFFICULT TO ACCOMPLISH?  ...  An important part of using an SDM is knowing how and when to use modeling methods, how different models relate to each other, and how end users participate in creating the models and keeping the models  ...

Situation Models: An Avenue to the Modeling of Mental Models

Mica R. Endsley
2000 Proceedings of the Human Factors and Ergonomics Society Annual Meeting  
The concept of a mental model is well ensconced in the human factors literature.  ...  Through the situation model, a method for abstracting user knowledge and creating usable models of their mental model is explored.  ...  As SAGAT only requires that people report what they believe to be the state of the system, and not why they believe that to be the case, it is information that is readily reportable.  ...
