In order to deeply understand the current research situation of the mainstream active suspension system and its main control methods, this paper introduces 3 active suspension system including electric control hydraulic active suspension, electric control air suspension and electromagnetic active suspension, and analyzes 8 kinds of active suspension system control method containing PID control, state feedback H_∞ control, fuzzy control, neural network control, control of sliding mode control, adaptive control, robust control and prediction control. Compared with the advantages and disadvantages of different control methods, the paper suggests that the current active suspension and its control technology face challenges such as large energy consumption, low energy recovery, ideal simulation research conditions, the gap between the working conditions provided by the test equipment and the actual operating conditions of the actual active suspension, and the difficulty of multi-system fusion control. Finally, the future research direction and development trend of the control method of active suspension system are summarized.
