Functional Research of Networked Semi-Active Suspension System

The task is closely related to networked semi- active suspension control system. It is suggested to use an identification approach for damping parameter calculation of each wheel (quarter car model), then make regulation of only one parameter- damping one- according to current situation. To do that closed loop to adjust damping parameter accordance with desired reference signal is formed. Full structure of networked semi active suspension system using CAN bus protocol is presented. An additional task related with estimation of network influence on the performance of the whole combined damping system is also carried out, that the consideration of the network influence as a pure delay is approximate and doesn't take into account a lot of network functional features. Simulation of networked quarter car model together with feasible suspension control law, central processor and CAN physical model on the base of National Instruments equipment's was fulfilled. Experiments carried out with mathematical and physical models showed the workability of suggested solutions.
