Study On The High-accuracy Optical-electronic Measurement And Control System And Its Control Strategy

The optical-electronic measurement and control system is a main part of missile and space measurement and control system. It can get the information, trajectory parameter and characteristic parameter of the target by optical principle. It has high-accuracy and good directly perceived through the senses. Its main application are trajectory measurement, flying live recording and physics characteristic parameter measurement etc.. This dissertation is mainly focused on the research of high-accuracy optical-electronic measurement and control system and its control strategy on the background of a model optical-electronic measurement and control system.First, the research and development situation of national and international of optical-electronic measurement and control system is analyzed. The development characteristic in technology and structure form of optical-electronic measurement and control system is summed up. The development tendency in the future is forecasted.Second, the operation principle and measurement principle of optical-electronic theodolite are introduced. The "L" formula, "K" formula and "m" formula of optical-electronic measurement and control system for intersecting measurement are introduced. And the least square estimation method of multi-optical-electronic theodolites intersecting measurement is discussed.The overall design of the double reflector optical-electronic theodolite is studied on the background of "the X small remote-control optical-electronic theodolite". A new structure form of overall-layout-"hybrid-type" structureoptical-electronic theodolite is put forward. At the same time, the specific properties of image intensifier high speed photography system, the structure reliability of vertical shafting system are studied.The calibration method w ith star of optical-electronic theodolite is discussed. First, the star library and star table are set up by the detectability of "the X small remote-control optical-electronic theodolite ". Second, the effect o f each individual error to the measuring accuracy of optical-electronic theodolite is analysis. In the end, the method of resolving each individual error by the star data information is discussed, and the engineering application software system based on windows is given.The dynamics characteristic of optical-electronic theodolite is analysis, and the unlinear differential equations of optical-electronic theodolite is set up. The equations is simplified with concrete parameter of "the X small remote-control optical-electronic theodolite ". The mathematic model of optical-electronic theodolite control target is set up.The control strategy of optical-electronic theodolite is discussed. The method of decoupling-based adaptive fuzzy variable structure control is put forward, it is a new try of the control strategy for high-accuracy optical-electronic measurement and control system. At the same time, the effect of structure dynamics characteristic to the servo control system of optical-electronic theodolite is analyzed.Some simple conclusions are given in the last part of this dissertation.
