Integrated Chassis Control Using Inverse Nyquist Array Method

摘要

An integrated chassis control(ICC) system is introduced in this paper by the integration of the active front steering and brake systems based on the Inverse Nyquist Array(INA) Method.To deal with the interference and coupling issues between the two active control systems,the characteristic of the target vehicle was analyzed;an ICC controller was designed through INA method,to precompensate and dynamic compensate the vehicle system respectively,which can realize proper control allocation in hoth high-frequency band and low-frequency band.Some typical cases were simulated on a co-simulation platform with both MATLAB and AMESim software.Results show that the controller can decouple the systems and improve the vehicle handling and stability performance effectively.
