Provident control of an electro-hydraulic servo system
Proceedings of IECON '93 - 19th Annual Conference of IEEE Industrial Electronics, 2002A systematic approach for the solution of the output tracking problem of an electrically controlled hydraulic servo system is presented. Utilizing the theory of variable structure systems, feedback linearization and adaptation, high performance is achieved, which is demonstrated by experimentation. >

The Electro-Hydraulic Bending Moment Servo Vibration Damper
IFAC Proceedings Volumes, 1981Abstract In the metal cutting process, selfexcited chatter sometimes may take place and it may cause bad effects on the workpiece surface, on machine life and on the cutter. It is generated, first of all, by the extremely resilient dynamic stiffness in the structure of the machine tool; this is especially true when a boring bar is long and slender ...

Fuzzy logic controllers for electro-hydraulic servo-actuators
2012 International Conference on Applied and Theoretical Electricity (ICATE), 2012The paper presents two fuzzy logic controllers used for electro-hydraulic servo-actuators command. The first is a Mamdani proportional controller with seven membership functions both on input and output and the second is a Sugeno controller also with seven membership functions on input and output. One follows the possibility to obtain good performances
