| 摘 要： | 为解决可编程逻辑控制器（PLC）传统CPU难以实现电机运动控制的问题，提出了一种基于梯形图翻译形式以及梯级执行机制的DSP．PLC架构，通过一套具有运动控制特点的指令集实现了可编程控制器的运动控制功能，并给出了运动控制的关键技术前后台动态（FBD）调度算法。实验结果表明，DSP—PLC构架既发挥了DSP高速处理的优势，又体现了PLC图形化的编程特色，且调度算法简单有效，可适用于电机运动控制系统。

| Abstract: | In order to solve the problem that motor motion control is difficult to realize by traditional CPU of programmable logic controller(PLC),a DSP-PLC frame based on the form of ladder diagram interpretation and mechanism of step implement was proposed,and the motion control function was realized by a set of instructions with motion control features.The key technology of movement control function that fore-background dynamic(FBD) scheduling algorithm was also put forword.The experiment results show that the DSP... |
