| 1 | An experimental investigation on decoupling performance for a lateral axis micromachined gyroscope with varying environmental parameters显示文摘This paper carries out an experiment study of decoupling performance for a novel lateral axis micromachined gyroscope with varying environmental parameters. The non-ideal mathematical model for the coupling mechanism of the gyroscope is established through the gyro dynamic response matrix. The coupling components varying with ambient pressure and temperature induced by stiffness coupling,damping coupling and electrostatic force coupling are semi-analytically discussed. The overall coupling ratio is evaluated via experiments in the custom-built installation. The testing results show that the decoupling performance of the gyroscope is sensitive to the environmental parameters and all the non-ideal errors are determined as a function of ambient pressure and temperature. The coupling error varies from 0.05% to 0.25% within the pressure range of 100 Pa-100 kPa. The characteristics of coupling with temperature are measured from 20°C to 100°C with a variation from 0.35% to 0.41%. The results also indicate that within the range of measured ambient pressure and temperature,the minimum coupling ratio occurs at 100 Pa and room temperature. The overall performance of the gyroscope is tested under the pressure of about 2000 Pa and room temperature to achieve a relatively low coupling ratio. The scale factor is measured to be 7.8 mV(°) -1 s-1 with nonlinearity about 0.45% in the full-scale range of 600(°) s-1. The short-term bias stability is approximately 0.06(°) s-1(1σ) for 20 min with noise equivalent angular rate evaluated to be 0.077(°) s-1 Hz-1/2. | CUI Jian LIU XueSong GUO ZhongYang ZHAO QianCheng LIN LongTao YANG ZhenChuan HAO YiLong YAN GuiZhen | 2011 | Science China(Technological Sciences)2011，54，12： | 1 |

| 4 | A novel robust design method for the sense mode of a MEMS vibratory gyroscope based on fuzzy reliability and Taguchi design显示文摘This paper proposes a novel robust design method for the sense mode of a MEMS vibratory gyroscope based on fuzzy reliability and Taguchi design. The principles of fuzzy reliability and Taguchi design are both introduced and described in detail. Experimental results demonstrate that the signal to noise ratio of the robust design scheme is better than those of the other experimental schemes.Over the full temperature range from -40 to 80°C, the temperature sensitivities of phase margin, gain margin, sensitivity margin,the maximum amplitude of open loop system, bandwidth of closed loop system, and the performance function of the robust design system are all smaller than those of the original design system. Meanwhile, the temperature sensitivity of the bandwidth of the robust design system is improved to 126 from 1075 ppm/°C. Moreover, the bias drift over the full temperature range of the robust design system is improved to 61°/h from 179°/h. | HE ChunHua ZHAO QianCheng HUANG QinWen LIN LongTao YANG ZhenChuan ZHANG DaCheng YAN GuiZhen | 2017 | Science China(Technological Sciences)2017，60，2： | 1 |
