ABSTRACT
For pursuing high performance, the development of semi-active suspension control tends
to be complicated and ignores practicability. A new mixed control method effectively suppressing
vibration of the vehicle body in the whole frequency band is proposed based on
electromechanical analogy theory. Simulation results show that in comparison with passive
suspension, on a long slope bumpy road, the mixed control reduces body acceleration by
21.49% and the maximum amplitude by 22.40%. On a C class road, the mixed control reduces
body acceleration by 9.78%. Finally, an ECU hardware-in-the-loop test is conducted,
which verifies the effectiveness and feasibility of the new mixed control method.
