联合仿真技术在车辆稳定控制程序开发中的应用

该文首先介绍了目前车辆稳定控制程序的研究现状并提出了通过联合仿真进行控制策略开发的新思路，然后详细阐述联合仿真技术的实现原理及方法。接着设计了基于线性二次最优控制理论的直接横摆力矩状态反馈控制策略并引入横摆角速度和质心侧偏角的限值控制以提高车辆在危险工况下的稳定性及可控性。最后通过ADAMS／Car和Matlab／simulink的联合仿真验证了该控制策略的正确性，并为今后复杂机电系统控制策略的开发提供了一条新的途径。

Application of Co-simulation Technology in Vehicle Stability Control Programming

The article first introduces the state of the art of vehicle stability control program and puts forward a new idea of control strategy design through co - simulation, and the principle and method of this technology are also explained. And then the direct yaw moment control state feedback strategy based on linear quadric optimal control method is designed. Further the limit control of yaw velocity and side slip angle is introduced in order to enhance the vehicle stability and maneuverability in critical situations. At last the validity of this strategy is proved by means of cosimulation between ADAMS/Car and Simulink, which has provided a new way for designing complex electric - mechanic system control strategy in the future.
