Embedded Motion Control System Design and Optimization Based On DSP

Several key technology in designing motion controller based on DSP: the interrupt mechanism betw een DSP and FPGA bus controller,high-speed field bus technology,fixed-point DSP IQmath floating-point library optimization technology and motion control algorithm optimization process model.Finally,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.
