Power assembly semi-active suspension control system and method based on fuzzy PID control

The invention discloses a power assembly semi-active suspension control system and method based on fuzzy PID control, and relates to the technical field of fuzzy PID control. The system comprises two vibration acceleration sensors which are installed at the active end and the passive end of a suspension support respectively and used for obtaining vibration acceleration signals so as to calculate the vibration transmissibility; a feedback system; a fuzzy database is designed according to the characteristics of the suspension. A single PID controller is combined with a fuzzy algorithm, two acceleration sensors are used for monitoring the vibration acceleration of the active and passive ends of the suspension, the vibration transmissibility is obtained through calculation and serves as input data of a system feedback link, the data are processed through the fuzzy algorithm and then input into the PID controller, and automatic adjustment of PID parameters is achieved. According to the system, under different vibr
