Modeling and control of an electro-hydrostatic actuator [PDF]
Proceedings of the IEEE 1995 National Aerospace and Electronics Conference. NAECON 1995, 2002 Advanced electro-hydrostatic actuators offer a high degree of maintainability and combat survivability of aircraft flight control systems, because all the components necessary to operate the actuator are collocated with the actuator. The quantitative feedback theory robust control method is used to design a controller for the actuator.
