The invention patent with application number 201210054782.8 "Electromagnetic Energy Feed Type Semi-active Suspension Energy Feedback Damping Real-time Control Device and Method", and the invention patent with application number 200410013577.2 "Energy Feedback Electromagnetic Damping Device for Vehicle Suspension" have good However, since the motor is in an uncontrolled state, the motor can only generate a certain damping force according to the current speed and the current flowing into the energy storage unit. This damping force is not controllable and not the desired optimal damping force. Vibration effect is not good
The invention patent with the application number of 201410018159.6 "A Feed-type Electromagnetic Damping Vibration Reduction Control Method for Vehicle Suspension" determines the motor output damping force according to the speed and acceleration of the motor, which satisfies the effect of energy feeding, but the vibration isolation effect is not ideal

Abstract

Disclosed is an electromagnetic suspension vibration isolation and energy feedback coordinating control method. The working mode of a cylindrical linear permanent magnet motor is selected according to the relationship between the sprung mass velocity and the double-stator asymmetric cylindrical linear permanent magnet fault-tolerant cursor motor rotor velocity, a skyhook-groundhook combined control strategy is designed, and the thrust or braking force needed by motor output is determined. The motor feeds energy back to a storage battery in an electricity generation mode, and absorbs electric energy from the storage battery in an electric mode. By the adoption of the strategy, vibration in the vehicle running process is effectively absorbed, the driving and taking comfort, the running comfort and the control stability of a vehicle are improved, the absorbed vibration energy is stored in the storage battery, the energy consumption of an electromagnetic suspension system is greatly reduced, and the method has good application prospects.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic suspension, and more precisely relates to a coordinated control method of electromagnetic suspension vibration isolation and energy feeding, and is especially suitable for automobile electromagnetic active suspension systems. Background technique [0002] With the development of society and the advancement of science and technology, people have higher and higher requirements for ride comfort, safety and stability. As an important part of modern cars, the performance of the suspension system has a great influence on the ride comfort and operation of the car. Stability, etc. have an extremely important impact. Suspension can be divided into passive suspension, semi-active suspension and active suspension according to the working principle. Passive suspension is mainly composed of elastic elements and passive dampers. It has simple structure, reliable performance, and no energy consumption. ...
