| 摘 要： | 基干广义最小方差和一步超前预报理论,围绕三维型面扫描系统中所存在的周期性徽振动问题,提出了一种新的自适应振动主动控制算法.以C型臂式三维激光扫描系统为应用背景,基于来自于该系统的数据样本建立了系统的振动动态自回归滑动平均模型(ARMA模型).采用所提出的自适应控制算法对该模型进行了振动主动控制仿真研究.仿真结果验证了所提出的方案可以有效地抑制C型臂运动过程中产生的振动,提高系统的整体三维检测精度.

| Abstract: | Based on generalized least variance and optimal prediction theory, a novel adaptive vibration control algorithm is developed to restrain periodical micro-vibration in three dimension (3D) scanning system. Based on the sample data, which are from the C-arm scanning system, an autoregression and moving average (ARMA) vibration model is established and the successful simulation is obtained. The simulation results show that the presented scheme can control vibration effectively. Therefore, 3D scanning precision... |
