Abstract

The invention discloses a vehicle Inerter-Spring-Damper (ISD) suspension active control method based on single neuron PID control. The vehicle ISD suspension active control method based on single neuron PID control comprises the following steps of (1) establishing a 1 / 4 model of an ISD suspension; (2) determining vertical displacement of a pavement; (3) determining a vehicle suspension performanceevaluation index; and (4) determining a neuron learning rule and a learning algorithm. According to the vehicle ISD suspension active control method based on single neuron PID control, an ISD suspension system can be simply and easily enabled to adapt to environmental change to improve vehicle performance; and the vehicle ISD suspension active control method based on single neuron PID control provides a new research thought and direction for design and application of the vehicle ISD suspension, in particular for research on a controllable ISD suspension.

Description

technical field [0001] The invention belongs to the field of vehicle suspension system control, in particular to the vehicle ISD (Inerter-Spring-Damper) suspension system control using the inerter technology. The invention relates to a control method of a vehicle ISD suspension, in particular to a vehicle hydraulic-electric coupling type ISD suspension control method. Background technique [0002] Vehicle suspension refers to the general term for all force-transmitting connection devices between the body and the wheels, and its components usually include springs, damping and guiding mechanisms. Its main function is to transmit the force and moment between the body and the wheels, buffer the impact from the uneven road to the body, and ensure the smooth driving of the vehicle and the comfort of passengers. It is one of the key points in the study of vehicle system dynamics. [0003] Smith, a scholar at the University of Cambridge, proposed the idea of ​​an inerter in 2003, a...
