The electrically interconnected suspension (EIS) can control vehicles' multiple-degree of freedom dynamics by designing a proper electrical network that connects independent electromagnetic suspensions. However, developing an electrical network (EN) for passive EIS to deal with complicated vibration is challenging. This paper proposes an EN optimization methodology for the EIS and experimentally validates the effectiveness of the optimized ENs with a hardware-in-the-loop (HIL) platform. First, a half-car model with a passive EIS is built and analysed for the EN design. The candidate EN st...

This paper proposes a novel decoupling vibration control method for the semi-active electrically interconnected suspension (EIS) and develops a mechanical hardware-in-the-loop (mHIL) test platform to verify the effectiveness of the method. Firstly, according to the decoupling characteristic of the interconnected electrical network, the half-car model is divided into vertical and roll ones, and their frequency response could show the capability of EIS on vibration control. Then, two H∞ state feedback controllers are designed based on the decoupled model to acquire the ideal force and torque f...

This paper establishes a 7-degree-of-freedom full-vehicle suspension system with two 2-degree-of-freedom controllable electrically interconnected suspensions (EIS) to achieve the control effect of the entire vehicle. The motions between the sprung mass and unsprung masses are converted into electrical energy via the electromagnetic suspensions, and then the energy is electrically interconnected with the electrical network (EN). This research is based on the previous study of a 2-degree-of-freedom EIS system, which shows the vehicle performance at heave and roll is improved by controlling resis...
