摘要
考虑一个已经获得最优决策的PSIC问题。由于费用函数、完成事件所需时间和项目中事件总数三个参数或函数发生变化后,在保证费用最小化和尽可能只对原计划做局部修改的前提下,解决扰动恢复问题。首先对问题进行数学描述、分析和建模。然后再用扰动恢复理论对各种情况进行讨论。最后给出了各种情况的解决方案。
The control strategy is one of the key technologies of EPS system, and the assistance characteristic has great importance to the vehicle handiness and road feeling. Based on the EPS dynamic model and the 3-DOF full vehicle model, the EPS control strategy based on curved assistance characteristic is designed. Pylon course sla- lom situation is executed and the rusuhs shown that along with the increase in speed the handiness and road feeling are all decreased, and the curved assistance characteristic has the superiority to find the better balance between handiness and road feeling. It has engineering significance to the overall design, function enhancement and optimi- zation and steering manipulation and safety improvement, and also to the electric vehicle and its integrated chassis control system development.
