Abstract

This article describes a typical architecture of electro-hydrostatic actuator (EHA), and establishes its nonlinear accuracy model by block diagram, which contains the refeeding circuit and friction. Based on the simulation analysis of damping, static error and friction, this article utilizes the dynamic pressure feedback and gain variable strategy to design the controller in state space. The robust-test results indicate the influence of parametric uncertainness on system performance.
