Key words : acceleration and deceleration;direct convolution;trapezoidal curve;S curve;FPGA 0 引言 现代数控系统、工业机器人正向着高速和高精度的方向发展,而加减速控制算法在实现其运动的高速、高精度上起着至关重要的作用。哈尔滨工程大学郑金兴等[1]提出了基于梯形速度控制的变插补周期实时插补算法,该算法可...
此控制器的实现需要三个主要组件:S-Curve 算法块(蓝色)、FIFO 块(橙色)和包含向目标设备驱动程序生成脉冲的管理块(黄色)。 使用此实现版本的FIFO块是因为S曲线和管理块的频率不同。它充当一个缓冲区,使S曲线与管理器中的脉冲产生相兼容。管理器本身是几个功能的组合,其中最重要的是脉冲发生器或PWM,因为它将S...
