目标点跟踪法在DSP运动控制卡中的应用

Application of Objective Point Track Interpolation in DSP Motion Control Board

以直线插补和圆弧插补为例,阐述了目标点跟踪法插补原理。该插补算法运算简单,插补精度高,能够满足控制系统高速高精度的要求,且易于实现抛物线、双曲线、螺旋曲线等复杂曲线的插补。将该插补算法应用于DSP运动控制卡中,通过DSP产生脉冲分配,从而实现对控制系统运动过程准确、快速的控制。

The theory of objective point track interpolation by taking beeline interpolation and arc interpolation for instance were expatiated. This kind of interpolation had a simple operation and a high presion, and it was competent to satisfy the requirement of high precision and speed in motion control system. It can also easy to carry out the interpolation of parabola, hyperbola, helix curve, and so on. The motion control board sent out impulse based on the theory of objective point track interpolation, because it would make the motion control course exacter and faster.
