Title:
SEMI-ACTIVE COORDINATION CONTROL METHOD FOR VIBRATION REDUCTION AND POWER GENERATION OF MAGNETORHEOLOGICAL ENERGY-REGENERATIVE SUSPENSION
Document Type and Number:
WIPO Patent Application WO/2020/224231
Kind Code:
A1
Abstract:
A semi-active coordination control method for vibration reduction and power generation of a magnetorheological energy-regenerative suspension. A magnetorheological damper and an energy-regenerative generator are installed in parallel between the sprung mass and the unsprung mass, and a controller calculates a driving current required by the magnetorheological damper according to a vehicle operating state signal and a power generation state signal of the energy-regenerative generator which are acquired in real time, so as to achieve optimal coordination control over vibration reduction and power generation of the suspension. According to the method, an optimal control law for vibration reduction and power generation based on an adaptive energy distribution rate is proposed, a semi-active coordination control strategy for vibration reduction and power generation of a magnetorheological energy-regenerative suspension is designed in combination with an inverse magnetorheological damper model, optimal vibration reduction and power generation integrated suspension performance of a system can be achieved by controlling the magnetorheological damper, and the method is high in universality and easy to implement.
