Research on System Identification Based on Wheel Coupling Road Simulation System

The wheel coupling road simulation system can simulate the vibration environment of the vehicle and its key components under the actual road conditions. In vibration control, the result of FRF identification directly affects the quality of control. This paper adopted a modified non-parametric identification method to identify the FRF of the system. Moreover, uses the coherent function to evaluate FRF indentified and RPC algorithm to verify control precision. The simulation design is given blow.
