Here we present our works. Section 1 is the introduction. The friction and moment fluctuation of the motor at low speed for the optoelectronic system are tested out which are shown in section 2. We introduce a repeat controller to the system to compensate the low-speed disturbances in section 3. Concerning the stability  a filter is added to the repeat controller. The experimental results are discussed in section 4. Not only the repeat control can overcome some low-speed-disturbances  but is more useful when tracking a periodic input signal.   Exchange interaction and magnetic phase transition in layered Fe/Au(001) superlattices 期刊论文  OAI收割 PHYSICAL REVIEW B, 2000, 卷号: 62, 期号: 5, 页码: 3354 Wang, JT; Zhou, L; Wang, DS; Kawazoe, Y 收藏  |  浏览/下载：27/0  |  提交时间：2013/09/17 GENERALIZED GRADIENT APPROXIMATION  SPIN-FLUCTUATION THEORY  FIRST-PRINCIPLES  MONATOMIC MULTILAYERS  CURIE-TEMPERATURE  AB-INITIO  ELECTRONIC-PROPERTIES  FE FILMS  FCC-FE  IRON   Dynamic and static properties of polyoxymethylene chains 期刊论文  OAI收割 EUROPEAN POLYMER JOURNAL, 1999, 卷号: 35, 期号: 10, 页码: 1911-1917 作者:  Zhang, LX;  Xia, A;  Zhao, DL   |  收藏  |  浏览/下载：13/0  |  提交时间：2019/04/09 Monte Carlo Simulation  Relaxation Time  Bond-fluctuation Model  Static Properties   Statistical properties of quasiparticle spectra in deformed nuclei 期刊论文  OAI收割 PHYSICAL REVIEW C, 1999, 卷号: 59, 期号: 1, 页码: 215-220 作者:  Wu, XZ;  Gu, JZ;  Iwamoto, A;  Wu, XZ , Inst Atom Energy, POB 275 18, Beijing 102413, Peoples R China.   |  收藏  |  浏览/下载：23/0  |  提交时间：2012/08/29 Level Spacing Distributions  Fluctuation Properties  Single-particle  Heavy-nuclei  Shell-model  Chaos  Densities  Physics  Order   Spin-wave theory of ferromagnetic-antiferromagnetic double layers 期刊论文  OAI收割 Physics Letters A, 1996, 卷号: 224, 期号: 1-2, 页码: 137-141 G.
