结合自己开发的嵌入式PC数控实验装置,对现有加减速控制算法的比较研究,存在算法比较繁琐、编程复杂等不足,提出了嵌入式数控系统中一种新的加减速控制改进算法。该算法有简便、编程容易、实现快速、精确的位置伺服控制、机床运动的动态特性好等优点。通过对插补轨迹仿真和实例分析,证明了插补算法和加减速控制方法的正确、合理、有效。
Combined with the embedded PC numerical control experimental device developed by myself, this paper presents a new algorithm of acceleration and deceleration control in embedded CNC system based on the comparison of the existing acceleration and deceleration control algorithms, which has many disadvantages such as complicated algorithm and complicated programming. The algorithm is simple, easy to program, to achieve fast and accurate position servo control, the dynamic characteristics of machine tool movement and so on. The interpolation trajectory simulation and case analysis prove that the interpolation algorithm and the acceleration and deceleration control method are correct, reasonable and effective.
