针对永磁同步曳引机驱动的电梯,设计了以双数字信号处理器(DSP)为控制核心的电梯驱动控制系统,以提高电梯运行的安全性和可靠性。对硬件系统中的几个模块进行了具体设计,并对系统软件设计的主程序、速度环中断和电流环中断进行了介绍。最后给出了实际系统调试结果。
The elevator drive control system based on the dual digital signal processor (DSP) to permanent magnet synchronous traction elevator is designed in order to improve the safety and reliability of elevator. The hardware modules are proposed and analyzed in detail, and the main program, the velocity loop interrupt and the current loop interrupt of the control system are introduced. Finally, the experiment results are given.
