Abstract:
According to the characteristics of the large-scale model of semi-active suspension, an hierarchical controller is developed. By using the large-scale system hierarchical technique, the control structure is established. The platform of the control system for the suspension is built on ARM. Including the sub-system based on the fuzzy neural network and the sub-program of harmonization, the software is designed. The systematic damping coefficient of semi-active suspension is regulated. The test has been done on road. Result of the test indicates that the controller can meet the request of control system of semi-active suspension voluntarily.
Key words:
