Quantized Fuzzy Feedback Control for Electric Vehicle Lateral Dynamics

The problem of L-2-L(infinity )quantized feedback control for lateral dynamics of electric vehicles is investigated in this article, in which the nonlinear vehicle lateral is represented by the T-S fuzzy model. A novel Lyapunov function and two-step design strategy are introduced to design the controller and the quantizer, which guarantee the same L-2-L(infinity )performance as with out quantization. Compared with the existing results, the advantage of the proposed design strategy is that the coefficient can be set to change the adjustment range of the quantizer parameters, thereby reducing the conservative of the design. Finally, the co-simulation of MATLAB/Simulink and Car sim witha full-vehicle model is provided to demonstrate the effectiveness of the proposed design strategy.
