In a large-scale control system, the health monitoring subsystem could produce hundreds to thousands of system inputs. Using Matlab's Stateflow to implement supervisory logic that could interpret sensor or actuator failures allows for a hybrid control system to be developed and simulated. The manual creation of a Stateflow chart for use in a Simulink simulation of a large-scale guidance and control system is a tedious and time-consuming process. The Stateflow Autocoder is a Matlab based software tool for the automatic generation of a Stateflow chart from information contained in a database. Managing the parameters and elements of a simulation via a database presents an opportunity to efficiently create or modify a simulation model by only changing information that is contained within the database. This paper describes the auto-generation of a Stateflow chart that is required to manage a simulation from a database.
