This paper describes the controller design scheme for the hydraulic system in Direct Yaw Moment Control (DYC) System for a front-engine front drive vehicle. Regardless of the hydraulic system's characteristics changes over a wide range of operational conditions, the hydraulic system is required to achieve the desirable speed of response and stability. This paper, therefore, proposes a two-degree-of-freedom hydraulic control system consisting of reduced-order controllers to satisfy these requirements. From the results of proving ground tests, it is confirmed that the proposed control system satisfies the requirements imposed on the hydraulic system for a DYC system. |
