【Abstract】 Correlative identification is an identifica-tion method in time domain. Applying the fu-ndamental principle of correlative identification, the math model creation of electro-hydrau-lic servo system for swing angle mechanism in variable displacement pump is analysed theore-tically andstudied experimentally. Through ac-tual measurement and computer simulation of the system, the feasibility of the model created has been validated and on the basis of this model, the simplification of the higher order model of the system is describes. The dyna-mic performance of the system has also been studied.更多还原
