Optical grating bit shift detection control system , and digital closed - loop servosystem , which controlled by the computer , can communicate mutually , exchange data and transmit control information . overall system can achieve the high accuracy position 光柵位移檢測系統(tǒng)和閉環(huán)伺服控制系統(tǒng),是由微機(jī)來控制的,它們可以通訊,以交換數(shù)據(jù)或是傳遞控制信息,實(shí)現(xiàn)高精度的定位
Firstly , we introduce some conception and general design theory of ate , then we analyze the construction and signal forms of these instruments , especially on its main functional block , servosystem ' s working principle and signal form 文中首先介紹了ate的概念及其一般性設(shè)計(jì)方法,然后就航空儀表的結(jié)構(gòu)原理與信號要求,特別是其主要功能單元?隨動系統(tǒng)的工作原理與接口信號形式進(jìn)行了重點(diǎn)分析。
According to different signal forms , we plan for the execution methods of three test items : servosystem performance , discrete signal input , discrete signal output . , and decide the necessary modules which this ate is composed of 按照測試信號流程劃分了三類測試項(xiàng)目?隨動系統(tǒng)性能檢測、離散信號輸入測試、離散量輸出測試?擬定了相應(yīng)的實(shí)現(xiàn)方案,在此基礎(chǔ)上確定了構(gòu)造這臺ate的所需的硬件單元。
As a hardware . the gimble servosystem design is very important in the making of the optoelectronic tracking system . the precision of the position . speed and the speed stability are the key indexes . for the optic measurement system in the high space . the minimum stable speed and high precision are needed 轉(zhuǎn)臺伺服系統(tǒng)的位置精度,速度精度和速度平穩(wěn)性是光電跟蹤系統(tǒng)設(shè)計(jì)的重要指標(biāo),而對深空光測系統(tǒng),則要求其具有穩(wěn)定的最低速度以及低速時(shí)高的工作精度。
