摘要
基于顺馈控制原理提出前向差分控制算法，详细讨论了这种算法的控制机理和实现问题，实验表明前向差分控制算法构造简单，且能大幅度减小斜坡输入位置稳态跟踪误差。
A positioning controller in CNC system using forward differential is presented based on forwardfeed control.The mechanism and the implementation of this method are discussed in detail.Finally,the experiment results show that this controller not only is constructed simply,but also can sharply reduce the stationary error with slope input compared with the conventional approach such as PID control.
