摘要
针对汽车电动助力转向系统是一个非线性的多输入多输出系统的特点 ,提出了H∞ 鲁棒控制方法 .首先对电动助力转向系统的动力学模型进行不确定性分析 ;然后建立了系统状态空间方程和增广被控对象矩阵 ;在此基础上用H∞ 方法极小化系统中各种干扰对被控输出的影响 ,最后通过计算机模拟的结果表明 。
Aimed at the nonlinear MIMO system EPAS, the H ∞ Robust Control method was employed to design controller. The uncertainty analysis of the EPAS was introduced. The state space formulation and the extended controlled object matrix were determined. Based on this matrix, the H ∞ method was introduced to minimize the effect of disturbances on outputs. The program for designing the robust controller was given. The simulation results show that the controller improves the performance of EPAS and its robustness.
