An improved anti-disturbance strategy is proposed to guarantee lateral stability for electric vehicles with external disturbance and input time delay.Firstly, the T-S fuzzy model is applied to describe active front wheel steering Android Auto Interface system (AFS).Based on the obtained model, a new collective observers including disturbance observer and state observer are structured to estimate 343 disturbance and state simultaneously.Then, a compound control is designed by using the estimation values of collective observers.During the design process, a novel path-independent fuzzy Lyapunov-Krasovskii function (FLKF) and slack variable matrices are introduced to reduce conservatism.

Finally, two simulation cases are implemented on Matlab/Simulink-Carsim to show the effectiveness of the proposed method.
