Abstract: Aiming at some shortcomings in the traditional embedded software design, such as low reliability and poor quality, a design method was presented that combines unified modeling language with Simulink Toolbox, and it is applied to the development of underwater winch control system. Using Simulink/Stateflow, the state machine model based on UML was validated by functional simulation, and the model was converted to ANSI C code that runs on the embedded hardware platform by means of Simulink/Embedded coder. The results indicate that the generated code can accurately control the underwater winch to realize working in a variety of operating conditions and multi mode switching operation, and this design method is superior in development efficiency, maintainability and reliability.
