Analysis and control of semi-active suspension system for a quarter car model

The objective of this paper is to analyze and control of semi-active suspension system for a quarter car model. The model of system is developed in SIMULINK. The performance characteristic of semi-active system is analysed in terms of ride comfort and its road holding ability. These characteristics are determined in terms of body acceleration, relative tyre force and relative wheel deflection by using different control strategies like PID, Neural Network and ANFIS. The results obtained by each controller is compared and analysed. The results indicate that the semi-active suspension system provides balance between ride comfort and road holding. ANFIS control provides better ride comfort as compared to Neural Network and PID.
