Research on Control Strategy for Active Suspension Based on Inertial Control Theory

摘要

For the purpose of solving the widespread problem of system response delay in traditional active suspension, this paper presents a new control strategy based on the measuring method of vehicle attitude described in the inertial control theory. The principle of Decentralized Control of Large-scale System is also applied in this strategy to decouple the vehicle attitude so that the extension length of hydraulic cylinder of each actuator and reactive force of each suspension can be calculated. Finally, a co-simulation platform based on AMESim and Simulink is applied to test the active suspension under this control strategy, and the result verifies that this control strategy can make active suspension response fast and restrain vibration of vehicle effectively.
