Study on PID Control Strategy of Active Suspension

摘要

This paper presents the mathematical models of passive suspension based on a 1/4 vehicle model and the analysis of ordinary structure active suspension model and the description of the dynamics equation further. The PID control strategy and system simulation based on the testing platform of the suspension system are discussed in this paper to analyze the control and design regulation of the PID controller in theory. The result shows that the dynamics model and the control strategy are feasible and available by the modeling in theory, the research of control regulation and the test examination.
