Fuzzy cerebellar model articulation controller (FCMAC) for vibration control on ocean engineering vehicles

摘要

In this paper, it was studied the semi-active quarter-coach suspension based on ocean engineering vehicles. The physical model of semi-active quarter-coach suspension was established based on the theories of Buckingham's Pi theorem. According to the characteristics of the semi-active suspension, a new intelligent control algorithm based on the Fuzzy logic control and cerebellar model articulation control techniques-Fuzzy cerebellar model articulation control (FCMAC) was presented and used to perform online control of semi-active suspension for the first time, novel weight-update laws were derived that guarantee the stability of closed-loop system, both information retrieval and learning rules were described by algebraic equations in matrix form. The results of experiment of closed -loop excited by three typical vibration signals showed that FCMAC control strategy can reduce the value of mean square root of vertical acceleration of semi-active suspension system to be lower 23%, 25% and 18% compared with the traditional control strategy such as PID.
