| 英文摘要 |
| The electro-hydraulic brake system (EHB) has become an increasingly promising research area. In this
paper, the pressure control method of a self-designed I--EHB (integrated electro-hydraulic brake) system were researched
to ensure the dynamic response of the system, and to balance the delay and loss of energy during work. Therefore, two
hydraulic pressure control methods, the optimized self-adaptive PID control based on the Taguchi method and the sliding
mode variable structure control (SMVSC), were designed and experimented on test bench. The paper compared these two
different control methods and the experiments revealed that the EHB system with SMVSC has shorter time delay, smaller
steady state error and better robustness with respect to integral controllability, especially when the target output is low
frequency average-high hydraulic pressure, which occurs mostly under normal working condition. Therefore, this paper
showed the effectiveness of the SMVSC and guides the further investigation of the hydraulic pressure control method. |
