Treffer: PI and fuzzy logic controllers for electro hydraulic servo system.

Construction, transportation, and manufacturing are just a few of the uses for hydraulic systems. For optimum performance and efficiency, hydraulic systems depend on control algorithms to govern variables like displacement, velocity, and pressure. In hydraulic systems, proportional-integral (PI) control is a popular kind. These control algorithms' unique design and calibration determine how they affect the displacement signal from the hydraulic system. When PI controllers are used in hydraulic systems, the introduction of integral terms lengthens the system's settling time and slows down the reaction time overall. The position to which the hydraulic piston goes in terms of displacement and where its speed gradient is regulated. Fuzzy logic and MATLAB functions were employed as the controllers. According to the findings, fuzzy logic is the best controller. Additionally, the outcome demonstrates that the value of the cut-off displacement signal fluctuates over time across the various components of a hydraulic cylinder's movement signal. Artificial intelligence was the most effective algorithm, with a maximum speed of 100 cm/s. [ABSTRACT FROM AUTHOR]
