Projective control of electro-hydraulic servo system
Proceedings of the 2001 American Control Conference. (Cat. No.01CH37148), 2001A nonlinear dynamic model for an electro-hydraulic servo system is developed. The model's response is compared with that of an actual valve. A projective control algorithm is used to control the motion of a load. Robustness of the control algorithm is analyzed through simulations.
