The electric power steering (EPS) system has a very small phase margin and it is particularly easy to start oscillation. Therefore, a stable controller is needed to improve the stability margin. In addition, the gain of the torsional moment diagram of the EPS system in different situations exhibits parameter perturbation, which requires the control design to have certain robustness performance and consider all the stability margin, robust performance of the system and the bandwidth requirement of the system. In this paper, the fixed-order H∞control design is adopted to form an H∞optimisation matrix with multi-dimensional performance output and a third-order fixed-order H∞controller is designed. The controller has good robustness performance, high stability margin, and relatively low order compared to the conventional H∞controller design, which is convenient for practical applications. |
