Design of washout filter algorithm for land and water tank motion simulation

During the course of the motion simulation on land and water tanks, the limited workspace of the motion simulator always restricts the fidelity of the motion simulation. For the above phenomenon, a kind of tank motion simulation washout filter algorithm was put forward, and a platform tilt-coordinate maneuver was used to simulate the low frequency motion cueing and high-pass filter method was used to attain the high frequency motion cueing. This algorithm was analyzed by combination with a drill duty of tank, and the influence of the coefficients adjustment upon the simulator motion cueing was revealed. This algorithm shows good practicability by off-line test, and its advent is practically significant for the improvement of land and water tanks motion simulation performance.
