Most flight simulator adopt the Stewart platform as the motion base, which is composed of a moving platform linked to a fixed base through six extensible legs. Keywords: inverse dynamics control, H ∞ theory, flight simulator motion base, Stewart platform Describing function, acceleration step response and some maneuvers computed from the washout filter were used to evaluate the performance of the controllers. Forward and inverse kinematics and full dynamic model of a six degrees of freedom motion base driven by electromechanical actuators are briefly presented. The control strategy is designed using H ∞ theory. The control strategy is applied in the outer loop of the inverse dynamic control to counteract the effects of imperfect compensation. Imperfect compensation of the inverse dynamic control is intentionally introduced in order to simplify the implementation of this approach.
The purpose of this study is to apply inverse dynamics control for a six degree of freedom flight simulator motion system.
