摘要
在双轴二维硬件直线插补算法的基础上,提出了不同于常用的、双轴二维电机同时加减速的控制方法,采用CPLD作为硬件设计、实现了双轴加减速控制器。经过环形分配器及放大电路控制二维(X向,Y向)步进电机,实现机床高速加工启动和停止时速度的稳步过渡。仿真结果显示控制效果良好,验证了该控制算法的有效性。
Based on the linear interpolation algorithm of double-axis and two dimensional, a new control method for double-axis step motor accelerating and decelerating at the same time was put forward, and the hardware on CPLD was realized.By two stepper motors directed to X and Y controlled through a set of circular distributor and driving-circuit, a transition may be steady between the starting and stopping with high speed.The simulation result gives good control effect, and shows the effectiveness of this algorith...
