Abstract

Active suspension systems with permanent magnet (PM) linear motors can regenerate vibration energy from road impact and demonstrate a potential application in vehicles. In this chapter, a linear quadratic regulator (LQR) controller of active suspension is designed in which a set of the optimal weight coefficients is obtained by means of particle swarm optimization (PSO) method. A novel and intelligent multi-mode switch control strategy is proposed to regenerate vibration energy from road impact and maintain a balance between energy regeneration and vibration isolation in suspension systems. Semi-active regeneration mode and active vibration isolation mode can be switched continuously according to the preference of the driver and the actual driving conditions. The simulation results show that the proposed multi-mode switch control strategy can reduce road impact and improve ride comfort and road holding substantially. On the other hand, it can also enhance energy regeneration intelligently. The effectiveness of the proposed control strategy is thus analyzed and verified.
