Experimental device for testing of servomechanisms of the passive optoelectronic rangefinder

Abstract eng:
It is necessary to use quite a big gear ratio (from 150 to 300) to ensure an accurate control of the angular motions of passive optoelectronic rangefinder (POERF). Used zero-backlash gearings together with the features of rolling-contact bearings generate relatively high nonlinearities which make the achievement of demanded control accuracy of POERF complicated or even totally precluded. Experimental (Test) device for the described drives was constructed in OPROX company. The device was set into function by the composite authors of this article and at the moment, relevant measurements are being taken. The aim is to use the testing measurements taken on the device in order to design and verify a method and SW for initial and continuous identifications of the parameters of POERF nonlinear model of servo-drive. In this article we will provide basic information on mechanical design of the experimental device construction, control and power parts of servo-drive and on communication protocol including the measurement protocol (output data).
