Robust control design of an electro-hydraulic actuator [PDF]

2014 IEEE/ASME International Conference on Advanced Intelligent Mechatronics, 2014
The paper proposes a hierarchical control design of an electro-hydraulic actuator. The high-level hydromotor is modeled with a linear form with parametric uncertainty, while the low-level spool valve is modeled with a polynomial system. The subsystems require different control strategies.
