摘要
针对锁相环在大、中功率调速系统中的一些缺陷,本文提出了基于数字信号处理器和复杂可编程逻辑器件的控制器和锁相环路的一种新的设计方案,使锁相环具有新兴的控制方法、DSP强大快速的数字处理功能、CPLD的灵活性等优点,提高了整个调速系统的稳定性能。
According to the disadvatange of PLL(Phase-Locked Loop) in speed system, this paper presents a new design scheme based on DSP (Digital Signal Processor) and CPLD (Complex Programmable Logic Device),Which combine PLL with new control arithmetic,fast digital signal process function of DSP、agility of CPLD to improve stability of the system.
