Abstract EN
In order to effectively improve vehicle riding comfort, handling stability, and realize vibration energy recovery, a new kind of electromagnetic linear hybrid active suspension (EMLHAS) integrated with linear motor and solenoid valve shock absorber is put forward.
Firstly, for the analysis of the suspension performance, a quarter dynamic model of EMLHAS is established.
At the same time, the mathematical models of a linear motor, including the active state and energy-regenerative state, are found.
The correctness of mathematical models for the linear motor in the active and energy-regenerative states is verified by means of characteristic tests.
Moreover, the velocity characteristic tests of solenoid valve shock absorber are carried out to determine its mathematical polynomial model in the semiactive state.
Then, a new kind of multimode endocrine composite skyhook-groundhook control strategy is proposed.
The suspension motion is divided into four modes according to the driving conditions of the vehicle.
An endocrine control with long feedback and short feedback is combined with the skyhook-groundhook control.
The control laws of the skyhook-groundhook controller and endocrine controller are, respectively, designed.
Finally, the simulation analysis of suspension dynamic performance and energy-regenerative characteristic is done.
The results show the control effect of endocrine composite skyhook-groundhook control is better than that of skyhook-groundhook control, which improves vehicle riding comfort and handling stability.
Moreover, part of vibration energy is recovered.
