Abstract

The invention discloses a feed-type electromagnetic damping vibration attenuation control method for a vehicle suspension. The method is applicable to an electromagnetic damping vibration attenuation device formed by a cylindrical fault-tolerant permanent-magnet linear motor, a motor controller, a speed sensor and a storage battery. Since the motor controller figures out the speed and the acceleration of the cylindrical fault-tolerant permanent-magnet linear motor according to the signal of the speed sensor, calculates the proportionality coefficient Kp and the integral coefficient Ki of a variable parameter PI based on the absolute value of the acceleration in real time and controls the cylindrical fault-tolerant permanent-magnet linear motor to run by adopting a speed closed-loop vector control strategy, the electromagnetic vibration attenuation function is realized, the vibration energy is recovered, the electromagnetic damping coefficient can be adjusted in real time according to the actual situation, the vibration attenuation performance of the suspension and the smoothness of a 'man-vehicle' system are improved and the energy is saved.

Description

technical field

[0001] The invention relates to a feeding type electromagnetic damping vibration reduction control method, in particular to a feeding type electromagnetic damping vibration reduction control method for vehicle suspension. Background technique

[0002] During the driving process of the car, the vibration of the wheels, engine, transmission system, etc. will be caused by the uneven road surface, the change of the speed and the driving direction. Stability, smoothness, and driving comfort, so the suspension as a vibration-reducing and stabilizing component is essential.

[0003] The suspension is used to elastically connect the frame and the axle, ease the impact on the vehicle during driving, ensure the integrity of the cargo and the comfort of the personnel, attenuate the vibration caused by the elastic system, and transmit vertical, longitudinal, and lateral reaction forces and moments , and make the vehicle body jump relative to the vehicle body according t...
