The electrically interconnected suspension (EIS) is a novel suspension system that has gained attention due to its potential to improve vehicle vibration control. This article provides a comprehensive review of EIS and related technologies. It starts with an overview of the research on hydraulic interconnected suspension (HIS) and its limitations. Then, it discusses the development of the electromagnetic suspension (EMS) and its advantages in adjusting mechanical characteristics. The article focuses on the electrical network and decoupling control characteristics of EIS, demonstrating the prin...

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...
