Abstract

The invention discloses an automobile ASS and EPS integrated system neural network inversion controller and a construction method thereof. An ASS and an EPS serve as a whole to constitute an entire automobile nonlinear system, neural network inversion is placed in front of the entire automobile nonlinear system, the neural network inversion and the entire automobile nonlinear system are connected in series to be compounded into a pseudo-linear system, on this basis, a linear closed loop regulator is designed for the pseudo-linear system, and the neural network inversion and the linear closed loop regulator are connected in series to constitute the automobile ASS and EPS integrated system neural network inversion controller. By the adoption of the controller, non-linear decoupling control over the automobile acceleration, the side tilting angle, the suspension dynamic deflection, the entire automobile yaw velocity and the centroid offset angle of an automobile can be achieved, and the control performance of an automobile ASS and EPS integrated system can be improved obviously.

Description

technical field [0001] The invention belongs to the technical field of vehicle engineering equipment, and relates to a neural network inverse-based automotive ASS and EPS integrated system controller and a control method thereof, which are suitable for high-performance integrated control of the nonlinear system of the entire vehicle. Background technique [0002] With the continuous development of science and technology, people have higher and higher requirements on the performance of automobiles such as maneuverability, ride comfort, comfort and driving safety. The active suspension system (Active suspension system, ASS) can effectively reduce the excessive acceleration of the vehicle caused by the irregular excitation of the road under various working conditions, thereby improving the driving comfort, improving the handling stability and smoothness of the vehicle, and has been It has become one of the research hotspots of scholars at home and abroad. As a new type of stee...
