[0099] Carsim and Simulink co-simulation implementation such as image 3 As shown, the vehicle model adopts the existing ones in Carsim: C‐Class, Hatchback model
[0100] C f =21803,C r =21803,l f =1.016m,l r =1.564m
[0101] I z =1536.7kgm 2 ,V x =10m / s, m=1270kg
[0102] can get:
[0103]
[0104] Use the feasp method in the LMI toolbox to obtain a feasible solution:
[0105]
[0106] W * =[-3.7206 13.4245 -7.2804 38.0960]
[0107] K=W * (X * ) -1 =[-2.3394 0.0135 -3.1629 -0.0075]
[0108] The simulation results are shown in the figure Figure 4 shown.
