基于DDS的高速伺服位置参数高精度控制算法
摘要
对于位移、速度、加速度的分别校准目前已经达到了一定的水平
但对于同时校准位移、速度、加速度难度较大
基于傅里叶级数的基本原理
即凡是满足狄利克雷条件的信号均可用若干个正弦分量叠加产生
设计了一套运动装置.该装置可以产生两个正弦分量
并通过正弦分量的叠加产生出一个信号.伺服电机采用超前反馈实现系统的运动控制
结合伺服电机变频调速
实现运动速度的平稳提升.测试结果表明:该装置同时产生0~460mm位移
0~12m/s速度和0~5 000m/s2加速度
速度、加速度的测量误差小于1%.该校准装置可以用于运动测试设备的校准.
Abstract
Currently the respective calibration for displacement
velocity
acceleration has reached a certain level
while the simultaneous calibration for them is still very difficult.Based on Fourier series principle
that is
for any signal it can be generated by several superimposed sinusoidal components
as long as it satisfies the Dirichlet
a set of apparatus was designed
which could generate two sinusoidal components
then produce a signal by superimposing these sinusoidal components.Advanced feedback control was utilized in servo motor to realize the motion control of the system
combined with frequency control
it could make the motion speed increased smoothly.The test results show that the range are 0~460 mm
0~12 m/s
0~5 000 m/s2 for displacement
velocity and acceleration
the error of the velocity and acceleration is less than 1%.The apparatus can be used to calibrate the motion test equipment.
