Embodiment Construction
[0032] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.
[0033] The energy-saving semi-active control method of hybrid electromagnetic suspension based on attitude compensation is mainly divided into the following steps:
[0034] Step 1. The front, rear, left, and right suspensions output the absolute speed on the sprung and the relative speed between the sprung and the unsprung to the semi-active controller, and the semi-active controller outputs the initial semi-active control force.
[0035] Step 2. Body output pitch angle θ and roll angle To the body posture controller, the body posture controller outputs the body posture compensation force Δf″ corresponding to each suspension LF .
[0036] Step 3. After adding the initial semi-active control force of each suspension and the body attitude compensation force of each suspension, divide by the relative velocity between the sprung and unspru...

The invention discloses a hybrid electromagnetic suspension energy-saving semi-active control method based on attitude compensation. The method includes: each suspension outputs absolute sprung speedZs and relative speed (Zs-Zu) between sprung speed and unsprung speed to a semi-active controller so as to output semi-active force; meanwhile, a vehicle body outputs the pitch angle theta and the roll angle phi to a vehicle body attitude controller so as to output the compensation force of the output force of each suspension; the semi-active force and the compensation force are added and then converted into equivalent damping Ceq, and a suspension controller is used to convert the equivalent damping Ceq into target currents Igoal; a motor controller is used to track the target currents so asto control a linear motor to output appropriate control force f. By the method, the energy feedback ability of hybrid electromagnetic suspensions can be maximized, passenger comfortableness can be improved, and vehicle body attitude can be controlled.
Description
technical field [0001] The invention relates to the field of automobile chassis control, in particular to an energy-saving semi-active control method for a hybrid electromagnetic suspension based on attitude compensation. Background technique [0002] my country's automobile demand and ownership are constantly increasing, resulting in energy shortages and environmental problems that have become increasingly prominent, and energy conservation and emission reduction has become one of the themes of today's automobile development. There is a large amount of energy loss during the running of the car, among which the vibration energy loss is converted into heat energy loss through the damper, accounting for about 20% of the energy loss of the whole vehicle. [0003] The electromagnetic hybrid suspension can recover part of the vibration energy through the linear motor to improve the fuel economy of the car, and can also actively output the control force through the linear motor to...
