摘要
为了解决数控系统中S型加减速算法解析式方法缺乏的问题,提出一种7段式S型曲线加减速控制算法。该算法将所有7段式S型曲线可能出现的情况归纳为11个一元多次方程,再利用求根公式得到加减速时间。自主研发一种多轴运动控制卡,验证了7段式S型曲线加减速控制算法的所有情况。验证结果表明:该算法简单有效、运行稳定,能够满足高速高精度数控要求。
For the lack of analytical method of acceleration and deceleration algorithm of S-shaped curve in NC system,this article proposes an acceleration and deceleration control algorithm of seven-segment S-shaped curve,which summerizes all the possible cases of the seven-segment S-shaped curve into 11 many times a dollar equation,and uses the root formula to abtain the acceleration and deceleration time.A multi-axis motion control card is independently studied and developed to verify all cases of the acceleration and deceleration control algorithm of seven-segment S-shape curve.The verification result shows that the algorithm is simple for application,stable in operation,which meets the requirements of high speed and high precision of numerical control system.
