基于DSP的发动机恒转速控制系统的研究

Study on Constant Engine Speed Control System Based On DSP

在小型发动机性能测试平台中,重新设计了电涡流测功机的控制系统,采用双闭环恒转速控制系统对发动机进行恒转速控制,解决了单环控制性能不佳的问题。介绍了系统的组成和设计,运用双闭环控制提高了控制系统的稳定性,并采用TM S320LF 2407 DSP芯片以提高系统的控制和处理能力。此外,着重介绍了DSP控制软件的具体设计方案,包括软件结构流程、中断处理、功能函数的介绍及控制算法的编写,为同类设计提供了一个良好的DSP软件解决方案。

In the performance test of the small engine, the double closed-loop control system can implement constant engine speed control. Structure and design of the system is introduced. Its stability is enhanced with double closed loop control. And the embedded chip TMS320LF2407 is used to enhance the controlling and processing capabilities of the system. In addition, software development is introduced in detail.
