Embedded Motion Control System Design and Optimization Based On DSP

分析了基于DSP设计运动控制器的几个关键技术:DSP与SSB-Ⅲ总线控制器的中断机制,高速现场总线技术,定点DSP的IQmath浮点库优化技术和运动控制算法的优化流程模型。最后针对影响运动控制器性能的中断延迟时间、运动控制算法数据精度和算法执行时间进行了评测对比,实验结果表明满足运动控制器的高精、实时等要求。

Several key technology in designing motion controller based on DSP： the interrupt mechanism between DSP and FPGA bus controller, high-speed field bus technology, fixed-point DSP IQmath float- ing-point library optimization technology and motion control algorithm optimization process model. Fi- nally, this paper completed the measurement of the motion controller performance and interrupt latency, and data accuracy and execution time of motion control algorithm, the experimental results show that can meet the high-precision motion controller, real-time and other requirements.
