	The effect of backlash nonlinear on resonance frequency of electric actuator transmission system (EI CONFERENCE) 会议论文 OAI收割 3rd IEEE International Conference on Advanced Computer Control, ICACC 2011, January 18, 2011 - January 20, 2011, Harbin, China Han X.; Ge M.; Bai Y.; Jia H.; Ge W. 收藏 \| 浏览/下载：25/0 \| 提交时间：2013/03/25 In order to study the effect of backlash nonlinear on resonance frequency of electric actuator transmission system then Finally in the premise of meeting the stability the dynamic equilibrium equation of transmission system with backlash is established it makes dynamic simulation analysis for the transmission system based on virtual prototype technology it establishes balanced equation of dynamics system with backlash the effect of backlash on system natural frequency and resonance frequency and the theoretical values and simulation values are compared. Theoretical analysis and simulation results show that the theoretical analysis is basically consistent with simulation results when it is zero backlash and does some theory research and dynamic analysis of backlash nonlinearity and system natural frequency and resonance frequency. First and the error of theoretical analysis and simulation results is within 10%. Therefore according to describing function to theoretically model the backlash nonlinear it can be concluded that considering the transmission system theoretical analysis of backlash nonlinearity is feasible the relation between describing function and the amount of backlash and input amplitude is analyzed and it is much closer to the actual system with instructive significance. 2011 IEEE.
	Distribution of gyroscope accuracy parameters for E-O stabilization platform (EI CONFERENCE) 会议论文 OAI收割 2011 International Conference on Electric Information and Control Engineering, ICEICE 2011, April 15, 2011 - April 17, 2011, Wuhan, China 作者: Zhang X.; Zhang X.; Zhang X.; Jiang H. 收藏 \| 浏览/下载：29/0 \| 提交时间：2013/03/25 E-O stabilization platform performance is partly decided by gyroscope precision so it is important to choose a gyroscope with proper accuracy for an E-O stabilization platform. Based on the method of using a gyroscope in practice gyroscope error model is established. With the gyroscope error model gyroscope accuracy parameters that is bias repeatability bias stability scale factor scale factor nonlinearity output noise and bandwidth are separately analyzed. According to the concretely required performance indices for an E-O platform means of distribution of gyroscope accuracy parameters is proposed. A MEMS gyroscope is tested to get the parameters. Bias stability of the gyroscope is 0.08 /s while the bandwidth is 60 Hz. Output noise both at zero input and at nonzero input is analyzed by means of PSD to get the result that nonzero output noise is higher than zero output noise. Frequency response result of the gyroscope is dealt by means of correlation analysis. With all the tested result and the method of distribution of gyroscope accuracy parameters it is clear that how the gyroscope errors works in an E-O servo system. The principle of distribution of gyroscope accuracy parameters is helpful for choosing appropriate gyroscope for an E-O platform. 2011 IEEE.
