The invention relates to a suspension control system based on a skyhook control algorithm. The suspension control system based on the skyhook control algorithm comprises a vehicle state sensor, a data collector, an industrial control computer, a magneto-rheological fluid damper, a motor driver and a servo motor, wherein the vehicle state sensor is used for detecting vehicle state data; the data collector is used for collecting the vehicle state sensor to obtain the vehicle state data; the industrial control computer is used for controlling the motor driver and a program-controlled current source according to the vehicle state data; the motor driver generates a driving force so as to drive the servo motor to generate a feedback effect on an active suspension of a suspension system; and the program-controlled current source generates a control current so that the magneto-rheological fluid damper generates a damping force to generate a feedback effect on a semi-active suspension of the suspension system. According to the invention, the running smoothness and the taking comfort of a vehicle body can be improved.
Description
technical field [0001] The invention relates to the technical field of vibration reduction control, in particular to a suspension control system based on a skyhook control algorithm. Background technique [0002] The dynamic suspension between the car body and the wheels is an important part of the vehicle. The performance of the suspension will directly affect the driving safety, ride comfort and handling stability of the vehicle during driving. The traditional passive suspension is composed of damping elements and elastic elements with invariable damping coefficient and stiffness. The passive suspension system needs to set the damping coefficient and stiffness before construction. Since the parameters are not adjustable after setting, they can only adapt to the vibration under certain working conditions, and have poor adaptability to changing driving conditions. The combination of active suspension and semi-active suspension can be adjusted according to the specific road...
