| 摘 要： | 无波纹有限拍控制器控制非最小相位对象时，会产生严重的瞬态响应，如负向超调和振荡．笔者利用参考输入前向通道附加零点配置技术，设计出了改进型无波纹有限拍控制器，该控制器不仅可以控制最小相位对象，而且可以控制一类具有位于右半Ｚ平面的共轭复数零点的二阶非最小相位对象－ 数字仿真表明，改进型无波纹有限拍控制器比原无波纹有限拍控制器具有更好的控制性能．

| Abstract: | The deadbeat controller working in controlling objects of nonminimum-phase, may cause severe transients, such as undershoots or oscillations for step response. A method of choosing additional zeros located in the set-point feedforward path is presented and an improved deadbeat controller is designed for not only minimum-phase system but also a kind of second order nonmunimum-phase system Digital simulation results show that the improved deadbeat controller works better than the original one |
