NONLINEAR MODELING AND CONTROL DESIGN OF ELECTRO-HYDROSTATIC ACTUATOR
Proceedings of the JFPS International Symposium on Fluid Power, 2008 In this paper, a typical architecture of Electro-Hydrostatic Actuator (EHA) is described and modeled by the block diagram based on mathematic equations, which is a nonlinear accuracy model. The single PID, cascade PID and state feedback controllers are respectively designed and applied to this model for comparison analysis that focused on system ...
