Multi-objective control design for a truck cabin

Abstract

In this paper, a multi-objective control of a three-degrees-of-freedom cabin model for a commercial truck excited by random road disturbances is studied. The multi-objective control problem is formulated as a non-convex and non-smooth optimization problem with controller order restricted to be less than the vehicle model order. For a range of control orders, controllers are synthesized by using the HIFOO toolbox. The simulation results show that the cabin vibrations are effectively suppressed by this methodology
