Research on Wheelbase Preview Control for Vehicle Semi-active Suspension Based on Neural Networks

Based on the model of the 1/2 vehicle semi-active suspension with wheelbase preview, combined with neural networks algorithm and PID control theory, a neuron adaptive PID control algorithm was put forward, and designed the single neuron PID controller of semi-active suspension based on wheelbase preview. The simulation calculation was done at different speed, the simulation results showed that, compared with the passive system, the semi-active suspension wheelbase preview neurons PID controlled system can effectively reduce vehicle vibration, compared with the neuron adaptive PID controlled system, the rear vertical acceleration and pitch angular acceleration decreased significantly at the lower speed, improved the ride of the automobile.
