| 中文摘要 |
| 随着人们对汽车操纵舒适性、安全性和节能等方面要求的提高, 鲁棒控制算法越来越广泛的应用于电动助力转向(EPS) 控制系统中. 针对高阶鲁棒控制器实时性差、成本高等问题, 提出最优平方积分误差(ISE) 模型降阶方法. 应用该方法对EPS系统鲁棒控制器进行降阶, 并与最优Hankel范数降阶法进行比较. 仿真结果表明, 最优ISE降阶方法具有更好的降阶效果, 降阶系统具有很好的鲁棒性. |
| 英文摘要 |
| To satisfy the demands of driving on cosiness, safety and energy conservation, the robust control algorithm plays an important role in the electrical power steering(EPS) control system. To improve the inherently poor real-time performances and reduce the high cost, we present a reduced-order method based on the optimal integral square- error(ISE) model, and apply this method to reduce the order of the robust controller designed. Both the analysis result and the simulation result show that the ISE method is superior to the Hankel norm reduction method in reduction effect and the robustness of the reduced-order system. |
