HIL simulation evaluation of a novel hybrid-type self-powered active suspension system

摘要

In this paper, a novel hybrid-type self-powered active suspension system is proposed. Proposed system differs from previous designs in several points. First of all, a hydro-electromechanical type linear actuator is specifically developed to reduce the effective inertia along suspension motion axis. Suspension control law is constructed by using a new energy-based optimal control method. In addition, power electronics module is developed and physically realized to include its dynamics in overall system performance. Beside the boundaries of analytical work, hardware-in-the-loop (HIL) simulation is performed to support the research with real world data. HIL simulation results show the energy regeneration and vibration suppression capability of proposed system.
