Abstract:To overcome the deficiencies of present proprioceptive simulation algorithms such as the classic al w ashout algorithm applied to the vertical vibration of high speed locomotive driv ing simulator, a new fuzzy selftuning washout algorithm was proposed. The fuzzy re asoning was made according to the vertical vibration sense error of driver betwe e n the real train and its simulator, and the input of real vertical vibrati on parameters of a locomotive, and as a result, the coefficients of filters were ad justed in real time. The numerical calculation shows the sensation error index o f the〖HJ2〗 fuzzy selftuning control washout algorithm decreases 1421 % compared with the classical washout algorithm. The fidelity of simulator was enhanced effectiv ely.
