应用输入成形方法抑制光头在定位时的振动．通过建立光学头机电系统的数学模型，对于无参数摄动和有参数摄动两种情形分别应用零振荡（ＺＶ）和零振荡加微分（ＺＶＤ）两种输入成形控制器进行振动抑制，计算机数值仿真结果表明，该方法对于抑制光学头定位过程中的振动具有较好的效果． Application of input forming method to suppress the optical head positioning vibration. By establishing the mathematical model of the electro-mechanical system of the optical head, two kinds of input shaping controllers, namely zero-oscillation (ZV) and zero-oscillation plus differential (ZVD), are respectively applied to the two cases with no parameter perturbation and parameter perturbation. Simulation results show that this method has a good effect on suppressing the vibration during the optical head positioning.
