摘要
设计了一种主动前轮转向的鲁棒性控制.考虑外部干扰和系统的不确定性,采用鲁棒线性二次型调节器(RLQR)对车辆稳定性进行优化控制,提高系统鲁棒性.多种情况下的非线性仿真结果表明,所设计的主动前轮转向鲁棒控制具有较好的控制特性,并能有效提高车辆的稳定性.
A new robust control of the active front steering (AFS) system was presented. The design adopts a robust linear quadratic regulator (RLQR) controller to improve the system performance due to the external disturbance and system uncertainties. The various nonlinear simulations show that the designed robust controller has good control performance and can efficiently improve the handling stability of vehicle.
