Software-in-the-Loop Simulation Environment Realization using Matlab/Simulink 2006-01-1470
This paper presents the Matlab/Simulink-based Software-in-the-Loop Simulation (SILS) tool which is the co-simulator for temporal and functional simulations of control systems. The temporal behavior of a control system is mainly dependent on the implemented software and hardware such as the real-time operating system, target CPU and communication protocol. In this research, the SILS components with temporal attributes are specified as tasks, task executions, real-time schedulers, and real-time networks. Methods for realizing these components in graphical block representations are investigated with Matlab/Simulink, which is the most commonly used tool for designing and simulating control algorithms in control engineering. These components are modeled in graphical blocks of Matlab/Simulink. In order to achieve a seamless development process from SILS to Rapid Control Prototyping (RCP), the SILS block set is designed to be able to support automatic code generation in C without tool changes and block modifications.
