摘要
分别针对系统惯量和摩擦阻尼设计了惯量补偿控制和摩擦阻尼补偿控制,并通过CATIA建模测量的方法来获得系统惯量的值,以此确定惯量补偿系数。通过EPS测控台试验测试系统的摩擦阻尼大小,以此拟合出正确的系统摩擦阻尼补偿系数值。为了验证EPS系统补偿控制策略的有效性,分别进行了仿真试验和实车试验。试验结果表明,EPS补偿控制策略有效地提高了转向系统的响应速度、转向轻便性以及回正性等动态性能,对汽车电动助力转向系统工作性能有一定的改善作用。
This dissertation designs inertia compensation control and friction damping compensation control. Catia is used to measure the inertia of system. EPS test table is used to measure the friction of system. The simulation and real vehicle test is im- plemented in accordance with the relevant national standards to verify the effectiveness of the EPS compensation control. The re- al vehicle test results show that the EPS controller can improve the steering portability and the return-to-center performance of the test vehicle.
