- The purpose of this paper is to analyze the characteristics of electro hydraulic force servo system, at the same time, considering the serious disturbance of the friction force in the electro hydraulic force servo system, the nonlinear factors in the controlled object are analyzed, then we consider that the fact is the problem that the range of parameter variation is large and the model is difficult to be precise. In this study, the classical control theory and linear dynamics theory are used to analyze the system; meanwhile, the nonlinear dynamic theory is adopted to solve the structure and parameters of nonlinear dynamics problems of electric hydraulic force servo system. In this study, we focus on the influence law of nonlinear friction on the dynamic characteristics of electro hydraulic force servo system, and reveal deeply the typical nonlinear dynamic behavior of the system. Finally, we design the system self compensation controller,and it can effectively compensate the considering problem of system friction disturbance. After observing the external friction force of the system, we use the system self compensation controller, to carry out the dynamic compensation for it. At the same time, through the theoretical analysis and experimental study, the suppression of the friction force disturbance by the system self compensation controller in the electro hydraulic force servo system is studied.
