This paper mainly discusses how to design a high stability current control power supply for laser gyro of double anodes and common cathode in north - finder based on ring laser gyroscope 論文主要闡述了尋北儀中雙陽(yáng)極共陰極結(jié)構(gòu)的激光陀螺高穩(wěn)定度穩(wěn)流電源的實(shí)現(xiàn)過程。
Being the main aspect of inertial navigation system , strapdown inertial navigation system ( sins ) based on ring laser gyroscope ( rlg ) has been applied in the refitment of service weapons and the development of new weapons 激光陀螺捷聯(lián)慣導(dǎo)系統(tǒng)是當(dāng)今慣導(dǎo)系統(tǒng)發(fā)展的主要方向之一,已經(jīng)廣泛地應(yīng)用于現(xiàn)役武器裝備改造和新型武器系統(tǒng)研制過程。
Last , large numbers of experiments about the control circuit of the mdrlg are done , the experimented results show that the digital control circuit met the requirement of ring laser gyroscope , and the control effect is better than analog circuit ’ s 最后,對(duì)激光陀螺數(shù)字控制電路做了大量的實(shí)驗(yàn)測(cè)試。實(shí)驗(yàn)結(jié)果表明,數(shù)字控制電路能夠滿足激光陀螺抖動(dòng)控制、穩(wěn)頻控制的要求,并且控制效果優(yōu)于模擬電路。
As the main research institute of ring laser gyroscopes in china , teaching and research section 208 , nudt , is always puzzled by the problem of null - shift in the process of developing mechanically dithered ring laser gyroscopes ( mdrlg ) . the problem is that the mdrlg ' s null shift equal to the integral times of dither periods when the sample time is set as integer dither periods 作為國(guó)內(nèi)激光陀螺主要研制單位的國(guó)防科大208室,在機(jī)械抖動(dòng)激光陀螺(機(jī)抖陀螺)研制過程中一直為零漂問題所困擾:實(shí)驗(yàn)測(cè)得機(jī)抖陀螺零漂為抖動(dòng)周期(采樣時(shí)間取整數(shù)個(gè)抖動(dòng)周期)的整數(shù)倍。
A ring laser gyroscope (RLG) consists of a ring laser having two counter-propagating modes over the same path in order to detect rotation. It operates on the principle of the Sagnac effect which shifts the nulls of the internal standing wave pattern in response to angular rotation.
