Some fuzzy controllers for electro-hydrostatic servo-actuator

The aims of this paper, are to obtain for an electro-hydrostatic servo-actuator, good performances, (time response and frequency characteristics), making it usable on aircraft, and a more simple configuration of the regulator, with a short computing time and a more simple program, in order to obtain a cheaper and more simple implementation. The strategy is to reduce the membership functions number of the fuzzy regulator keeping in the same time the requested performances of the servo-actuator.
