  • formal verification of a space System s user interface with the ivy workbench
    IEEE Transactions on Human-Machine Systems, 2016
    Co-Authors: Jose Creissac Campos, M F Sousa, Miriam Bergue C Alves, Michael D Harrison
    Abstract:

    This paper describes the application of the IVY workbench to the formal analysis of a user interface for a safety-critical Aerospace System. The operation manual of the System was used as a requirement document, and this made it possible to build a reference model of the user interface, focusing on navigation between displays, the information provided by each display, and how they are interrelated. Usability-related property specification patterns were then used to derive relevant properties for verification. This paper discusses both the modeling strategy and the analytical results found using the IVY workbench. The purpose of the reference model is to provide a standard against which future versions of the interface may be assessed.

  • Nonlinear Robust Approaches to Study Stability and Postcritical Behavior of an Aeroelastic Plant
    IEEE Transactions on Control Systems Technology, 2019
    Co-Authors: Andrea Iannelli, Andrés Marcos, Mark Lowenberg
    Abstract:

    Two approaches to tackle the nonlinear robust stability problem of an Aerospace System are compared. The first employs a combination of the describing function method and μ analysis, while the second makes use of integral quadratic constraints (IQCs). The model analyzed consists of an open-loop wing's airfoil subject to free play and linear time-invariant parametric uncertainties. The key steps entailed by the application of the two methodologies and their main features are critically discussed. Emphasis is put on the available insight on the nonlinear postcritical behavior known as limit cycle oscillation. It is proposed a strategy to apply IQCs, typically used to find absolute stability certificates, in this scenario, based on a restricted sector bound condition for the nonlinearity. Another contribution of this paper is to understand how the conservatism usually associated with the IQCs multipliers selection can be overcome by using information coming from the first approach. Nonlinear time domain simulations showcase the prowess of these approaches in estimating qualitative trends and quantitative response's features.

  • Measuring robustness of a fault tolerant Aerospace System
    Twenty-Fifth International Symposium on Fault-Tolerant Computing. Digest of Papers, 1995
    Co-Authors: C.p. Dingman, J. Marshall, D.p. Siewiorek
    Abstract:

    In commercial literature, the meaning of the term fault tolerant has become vague. We describe a System used to measure the robustness of a fault tolerant Aerospace System developed at IBM, present the data collected during the project, and report conclusions and areas for future work.

  • Developing an Aerospace System Software Using PBL and MDA
    Fifth International Conference on Information Technology: New Generations (itng 2008), 2008
    Co-Authors: João Carlos Silva Nobre, Denis Silva Loubach, Emilia Colonese
    Abstract:

    This paper reports a problem-based learning - PBL approach for the development of real time embedded software for the Aerospace sector, employing a commercial suite of tools that supports model-driven architecture - MDA projects. Using this approach, graduate and last-year undergraduate students in computer engineering of the Brazilian Aeronautical Institute of Technology (LTA) have developed an Aerospace System prototype during an academic semester.
