基于DSP实现的无差拍控制逆变器

摘要

It introduces the digital transient feedback in the through status and the calculation method of how to make the full digital deadbeat control of the inverter with the microprocessor's fast speed calculation function; describes how to realize the deadbeat control with the TI's newest DSP(TMS320F240)and the control process. Emulation and experiments show that it is characterized with fast transient response, high precision, low THD, etc.%介绍了一种通过状态的数字瞬时反馈，利用微处理器的高速数值计算功能实现逆变器的全数字化控制的无差拍算法以及利用TI的最新DSP(TMS320F240)实现无差拍控制的方法及控制流程。仿真和实验表明，它具有瞬时响应快、精度高、THD小等特点。
