摘要：
Effect of combination type of a static nonlinear link and a dynamic linear link on dynamic characteristics of a measurement system is studied in this paper. Three dynamic nonlinear models that can be simplified as the same static nonlinear model for static measurement and the same dynamic linear model for dynamic measurement are put forward. Their step response is simulated and three characteristic parameters are chosen for further analysis. All parameters are affected by the nonlinear coefficient for one model while only two ones are affected for others. The extent of effect is also sensitive to the damping ratio for all three models. The effect of the nonlinear coefficient varies after a link is added to totally compensate the static nonlinear model and the conclusion that a special compensation method for every combination type is necessary is substantiated. The method to identify combination type is given based on the variation of the parameters before and after the compensation.
