Integration of the CASTLE Simulation Executive With Simulink

Abstract

Public reporting burden for this collection of information is estimated to average 1 hour per response, including the lime for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing this collection of information. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burden, to Department of Defense, Washington Headquarters Services, Directorate for Information Operations and Reports (0704-0188), 1215 Jefferson Davis Highway, Suite 1204, Arlington, VA 22202-4302. Respondents should be aware that notwithstanding any other provision of law, no person shall be subject to any penalty for failing to comply with a collection of information if it does not display a currently valid OMB control number. PLEASE DO NOT RETURN YOUR FORM TO THE ABOVE ADDRESS. The Controls Analysis and Simulation Test Loop Environment (CASTLE) is a Navy in-house developed aircraft simulation executive application that has been in use at the Manned Flight Simulator (MFS) facility in Patuxent River, Maryland and elsewhere for over 15 years. In addition to supporting real-time hi-fidelity pilot-in-the-loop simulations in the MFS facility, CASTLE also includes integrated tools used for development and analysis of airframe simulations on various platforms. REPORT DATEMuch of the work with CASTLE includes exchanging and analyzing data with Matlab and Simulink. In support of recent flight controls projects at Patuxent River, there was a requirement to integrate Matlab-Simulink models with the CASTLE simulation. This led to the development of a new capability that enables a Simulink model to be modified and executed continuously with the CASTLE simulation, without having to exit and restart. The only interaction with CASTLE required by the user is to launch the specific airframe executable desired.
