Hydraulic Control Design and Modeling Techniques

摘要

This report details the analysis of a hydraulic actuator system. The analysis consists of designing control compensation by means of deriving a frequency response from a non-linear mathematical model and using classical control theory. This hydraulic actuator system will be used on the Turret Motion Base Simulator (TMBS) which is a unique six degree of freedom simulator being developed. A considerable effort is being made to develop analytical models of laboratory simulators so that a complete assessment can be made before testing is conducted. Analytical studies may point to various problems with the system and control design considerations may be made early in the development stage. The results of selected command signals representing terrain profiles can be simulated with the analytical model before being applied to the actual system. As the level of complexity in laboratory testing is increased the more important becomes analytical studies. (JES)
