内容简介：

摘 要 本文是一个直流调速系统设计。 以 TMS320F240 为主控制器，它功耗底，控制功能强，同时，配以相应的接口电路，包扩 D/A 转换器、触发电路等。 D/A 转换器及触发电路，实现整个系统控制量的输出，达到电动机调速的目的。 系统主电路形式采用三相全控桥整流电路，也增加了一些保护电路，如熔断器等 ， 采用双闭环调速，电流检测环节和转速检测环节，能获得良好的静、动态性能。 计算部分包括器件参数计算和 PID 参数的初值计算，应用了工程方法。采用 PID 控制算法。 设计采用了 DSP 控制器，可减少外部元器 件的个数，软件编程灵活，可靠性高。 关键词 ： TMS320F240 双闭环调速 控制算法 PID nts Abstract This article is a direct current velocity modulation system design. By the TMS320F240 primarily controller, its power loss bottom, the control function is strong, simultaneously, matches by the corresponding connection electric circuit, the package expands the D/A switch, triggers the electric circuit and so on. The D/A switch and triggers the electric circuit, the realization overall system control quantity output, achieves the electric motor velocity modulation the goal. The system main circuit form uses three-phase all controls the bridge leveling circuit, also increased some protection circuits, like the fuse and so on uses the double closed loop velocity modulation, the electric current examination link and the rotational speed examination link, can obtain good is static, the dynamic performance Calculates partially including the component parameter computation and the PID parameter starting value computation, has applied the project method. Uses the PID control algorithm. The design has used the DSP controller, may reduce exterior primary device the integer, the software programming nimbly, the reliability is high. Key word
