Central controller design for active suppension and avtive anti-roll bar systems on automobiles ABSTRACT The demand for cars around the world is increasing, of which two important criteria that customers want are the comfort and the road safety. Car manufacturers are also always aiming to improve the car quality with these two criteria. To improve the comfort criteria, the active suspension is the most effective solution, meanwhile for the road safety, it is the active anti-roll bar system. In this paper, the authors use the optimal control method LQR to build a central controller for these two systems to improve simultaneously the comfort and the road safety when the car is moving. The simulation results on the time domain and frequency domain clearly show the effectiveness of the proposed controller when reducing the desired signals by over 30% compared to the cars use the normal passive suspension system.
