Because the error of mechanical transmission exists, the precision by the traditional open loop control is difficult to be qualified in many fields. It is of great practical value and potential applying foreground to develop full-closed loop motion controller with great precision. 由于机械传动误差、干扰等问题的存在,传统的开环控制在很多领域已很难满足定位控制的精度指标,因此开发高精度的全闭环运动控制器具有非常重要的实用价值和广阔的应用前景。
The composition loop dimension and tolerance is calculated and adjusted in order to guarantee products to have qualified dimension. 通过组成环尺寸及公差计算,调整组成环的尺寸公差,以保证产品尺寸合格。
