A novel electromagnetic active suspension with an energy-regenerative structure is proposed to solve the suspension�s control\nconsumption problem. For this new system, a 2-DOF quarter-car model is built, and dynamics performances are studied using the\nvariable universe fuzzy theory and the PD control approach.A self-powered efficiency concept is defined to describe the regenerative\nstructure�s contribution to the whole control consumption, and its in fluent factors are also discussed. Simulations are carried out\nusing software Matlab/Simulink, and experiments are conducted on the B-class road. The results demonstrate that the variable\nuniverse fuzzy control can recycle more than 18 percent vibration energy and provide over 11 percent power for the control demand.\nFurthermore, the new suspension system offers a smaller body acceleration and decreases dynamic tire deflection compared to the\npassive ones, so as to improve both the ride comfort and the safety.
