针对驱动系统的非理想因素，提出轨迹点前馈补偿校准技术，详细阐述前馈质量和前馈延时系数校准算法，推导出加速度前馈校准流程，极大的提高控制系统的高速响应特性-The combined　movement　is　generated by　the　linear　motor　and the spindle　motor of　the table　of　CNC.　In　order　to　meet　high　speed、 high　precision　and　multi-degree　motion performance,　the　control　is　more　rigid、　multivariable、strong　coupling　of　the　nonlinear system control.
