摘要：

The model of 7-degree-of-freedom full-vehicle active suspension system was established, and the controller was then designed. On this basis, the characteristic variables was selected, and the three different domains were then divided. Through correlated function calculation, the H∞ extension controller was built. Under different schemes, the classic and extension domains were chosen as players for constructing the game matrices to obtain Nash equilibrium point of value domain division. The fuzzy control rules were utilized to dynamically adjust the classical and extension domains' boundaries to optimize the control performance of suspension H∞ extension control system. The MATLAB/Simulink was utilized to carry out the simulation and the simulation results were then compared. The simulation results show that compared with H∞ control, H∞ extension control could better improve the performance of active suspension system; H∞ extension controller by the value domain game could further improve the control performance of suspension system. © 2017, Editorial Board of Journal of Systems Engineering Society of China.
