Abstract: Aiming at the problem of writing a large number of codes in the traditional simulation, the model-based design was investigated. Simulink and TMS320 F28335 were used as the tool to establish the simulation platform of the executive motor. The corresponding model of the motor was built by the platform in Simulink. The target model was compiled. Then, the codes were generated automatically and downloaded to the target board. The angle change of the transducer was seen as the control source of the motor. By twirling the angular transducer, the output voltage was changed, thus the motor can be controlled. The voltage range of the target board was from zero to three. One volt and a half was set up as the reference of the motor′s direction. The direction was judged by comparing the actual voltage with the reference one. The results indicate that the method of model-based design shortens the development cycle, proving that the platform can control the motor effectively.
