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．
A non-ripple limited beat controller that controls non-minimum phase objects can cause severe transient responses such as overshoot and oscillation. The author uses the reference input forward channel additional zero point configuration technology to design an improved non-ripple finite shot controller, which not only can control the minimum phase object, but also can control a conjugate complex zero zero point located in the right half of the Z plane Second-order non-minimum phase object-digital simulation shows that the improved non-ripple limited-beat controller has better control performance than the original non-ripple limited-beat controller.
