Abstract

The electro-hydraulic semi-active suspension uses a hydraulic cylinder as the damping adjustment element. It has the advantages of high power density and high reliability, and is widely applied to SUV models. However, it has problems such as unknown road surface excitation and response lag, which will affect the performance of the semi-active suspension. Firstly, the dynamic model of the electro-hydraulic semi-active suspension is established, and the numerical solution of this model is obtained through MATLAB. Then, on the basis of the H2/H∞ algorithm, the delay factor is taken into account, and the control parameters dependent on H2/H∞ are obtained by means of linear matrix inequalities. Finally, MATLAB is used to calculate the damping force under the delay-dependent H2/H∞ semi-active control strategy under random road surface excitation. The results show that the delay-dependent algorithm can alleviate the problem of damping force variation caused by response lag, and it has a positive reference role for the development of intelligent transportation.
