Code generation method and implementation of inverter system based on DSP

逆变器系统属于混杂系统,智能控制及故障诊断的DSP代码开发周期长、效率低、实现比较繁琐。针对这一问题,提出利用Embedded Coder工具辅助DSP实现逆变器智能控制及故障诊断研究。Embedded Coder将建模工具Simulink、集成开发环境CCS以及DSP目标板完美链接,在Simulink仿真环境下即可实现DSP的操作与开发。介绍了逆变器结构和PWM触发控制原理,以及Embedded Coder实现PWM代码的生成方法。利用Simulink设计PWM代码生成模型,并利用Embedded Coder工具生成PWM执行代码,实现Simulink环境下DSP程序调试与逆变器系统开发。

Inverter system is a hybrid system. The DSP code of intelligent control and fault diagnosis has long development cycle,low efficiency, and tedious implementation. Aiming at this problem, employing Embedded Coder tool to assist DSP in realizing intelligent control and fault diagnosis of inverter is put forward. As long as Embedded Coder links the modeling tool Simulink, integrated development environment CCS and DSP target board perfectly, the DSP operation and development can be achieved in the Simulink simulation environment. This paper introduces the inverter structure, the principle of the PWM trigger control, as well as the PWM code generation method using Embedded Coder. The PWM code generation model is designed by using Simulink, and the PWM execute code is generated by utilizing Embedded Coder tool to realize DSP program debugging and inverter system development in Simulink environment
