Control System of Integrated Electro hydraulic Brake System Based on Chatter compensation

Abstract:

The characteristics of integrated electro hydraulic brake(I EHB) system were analyzed based on experiments and friction chatter compensation was proposed. Then, a mathematical model was built and experiments were conducted. The experimental results show that low speed creeping is eliminated by using the chatter compensation. Meanwhile, the linearity is increased and the dead zone during the conversion between pressure increasing and decreasing is eliminated. In addition, the cut off frequency is increased by 55.6% from 4.5 Hz to 7.0 Hz, and the tracking performance is increased by 30.9%, 59.5% and 47.8% for different aim signals.
