Development Of Three-phase Inverter Based On Simulink Model Automatic DSP Code Generation

With the development of inverter,the control of inverters is increasingly being implemented using DSP and other digital controllers.The more function of inverters cause the programming of the digital controller to be more difficult to write.How to speed up the programming of the control code and how to reduce the difficulty is an urgent problem to be solved.MATLAB/Simulink simulation software has been very mature,but the algorithm model of the Simulink is built only for the pure software simulation.The model can't be directly applied to the actual DSP digital controllers.After the verification of the algorithm in Simulink model,the algorithm code still needs to be write manually.How to accelerate the progress from the model to the practical application is still a problem to be solved.In this paper,the development of inverters based on the Simulink model automatic DSP code generation was proposed in order to solve the problem of the development of the inverter mentioned in the above.In this paper,a Simulink model of inverter is built,then the DSP code project and executable file is automatically generated of the model by the configuration of model parameters and necessary software.This method increased the practical application value of the model and accelerate the development progress of control code of inverter.It reduces the difficulty of code development of inverter and has great application value.In this paper,the three-phase inverter is developed based on the Simulink model automatic DSP code generation.The FOC model of the three-phase asynchronous motor was built and the DSP code was generated directly by the model.The corresponding hardware circuit was designed and the method in this paper was verified on the experimental platform.The feasibility and practicability of this subject are verified.
