Research on the Coefficients of Multi-node Bilateral Control Model Determined by Least Square Method

With the development of communication technology, information transmission between vehicles has changed from onboard sensors to wireless communication technology. Considering the change of information flow topology from bilateral control to multi-node bilateral control, the weight distribution of different vehicle node information in the control strategy has become a very important issue. In this paper, the symmetry weight is studied and the weight coefficients of vehicle nodes are obtained by using the least square method to approximate the design function under the premise of ensuring the stability. Taking into account the exponential function can have a rapid rate of change, this paper uses it as a design function to generate the weight coefficient of the vehicle node. The function can effectively improve the anti-interference performance of the system and promote the traffic flow to reach the stable state more quickly, which is verified by computer simulation.
