Abstract: In order to achieve attitude control of the six degrees of freedom Steward motion platform, as well as the real-time simulation cockpit sports attitude, Washout Filte filtering method was adopted in this paper as the somatosensory simulation algorithm. The algorithm is used to derive Washout Filter high-pass, low-pass filter transfer function into a differential equation algorithm and longitudinal acceleration tilt strategy, pitching strategies etc. Experimental examples are used to verify the correctness of the algorithm.
