In the latter , that is in two - position alignment , the method of wavelet analysis is used to filter the output signal of optic fiber optic gyro , at last , the direction cosine matrix is gotten , the inertial components are demarcated , 在自对准中,利用二位置初始对准,运用小波分析对光纤陀螺的输出信号进行滤波,并且确定初始方向余弦矩阵并对惯性元件进行标定。
Abstract : the water - saving solar hot - water heater is improved . the replacement of the two - position water and vapour valve of the water - saving solar hot - water heater by the two position automatic prot ection valve leads to the transition from hand to automatic protection 文摘:用自动保护双位阀替代节水太阳能热水器的通水输气两位阀,使节水太阳能热水器从手动保护过渡到自动保护,改进了节水太阳能热水器系统
Recently , a new kind , two - position and three - way solenoid valve with great rate of flow and high speed as well as its test bed has been developed by school of energy and power engineering , wuhan university of technology . results have shown that it can control the injection of the diesel engine preferably . the research work in this paper has been done concerning on the solenoid valve and its test bed , which is listed as following 武汉理工大学能源与动力工程学院为其所配系统开发研制的一种二位三通大流量高速电磁阀,具有响应快、流量大等特点,能较好的实现对喷油过程的柔性控制,同时,该院还开发了电磁阀专用的测试装置,本文的研究工作即是针对电磁阀及其测试装置的进一步优化而展开的,分别如下。
By means of temporary stability of combining drift coefficient of angle sensor and through missile rotating two - position measurement , measuring rotating angle between the two positions by vertical sensitive axis x , and sensing the changes of ground velocity component between the two positions by horizontal sensitive axis and z , the position of the component is determined to realize the azimuth alignment before launch of tactical missile 角敏感元件漂移系数具有短期稳定性,通过转弹前后两位置对组合的测试,垂直敏感轴计测转弹过程中两位置之间的转角,两水平敏感轴敏感计测地速分量在前后两位置的变化,由此计算出部件当前所在方位,从而实现战术弹射前的方位对准。
