双输入单输出模糊控制模式因缺少积分环节而导致系统鲁棒性相对较差 ,PID控制因系统辨识而导致动态响应相对较慢 .本文提出一种新的数控铣削加工过程恒力模糊 - PID复合控制方法 ,具有响应快和鲁棒性强等特点 .另外 ,对切深渐变和突变的两种工况进行了试验验证 ,效果良好 Due to the lack of integration links, the system robustness is relatively poor and the PID control is relatively slow due to the system identification. A new numerical simulation of constant pressure fuzzy-PID Control method has the characteristics of fast response and robustness, etc. In addition, two kinds of working conditions, gradual change of abyss and abrupt change, have been tested and proved to be effective
