Electro-hydraulic load simulation method for helicopter booster

摘要

In this paper we present an electro-hydraulic load simulation method for the helicopter booster. Based on electro-hydraulic servo control technology, we construct the load simulation system. And then, the mathematical model of load simulation system for the booster is built. The position servo system controller is combined of hysteresis compensation with PI controller and the force servo system controller is designed by servo-compensation and fuzzy PID controller. Finally, the performance of the proposed elector-hydraulic load simulation method is validated through the position tracking and load simulation experiments.
