SELF-TUNING FUZZY CONTROL OF ELECTRO-HYDRAULIC SERVO SYSTEM
Proceedings of the JFPS International Symposium on Fluid Power, 1996 This study deals with a self-tuning fuzzy controller (STFC) when it is applied to an electro-hydraulic servo system. The STFC has a hierarchic structure consisting of an algorithm being identical to a fuzzy controller at the lower loop, and a tuning algorithm accommodating the performance evaluation and parameter modification function at the upper loop.

Research on the electro-hydraulic servo system of picking manipulator
AIP Advances, 2023 To meet the demand for high-altitude fruit picking, a luffing mechanism system is designed and used to control the hydraulic cylinder. Combined with the performance index of the servo system, the fuzzy proportional–integral–differential (PID) is adaptive and strong, and the robustness of the picking robot is simulated. Using the MATLAB/Simulink module,
