摘　　要：直接横摆力矩控制DYC(Direct Yaw-Moment Control)是提高汽车操纵稳定性特性的重要方法,其研究对于提高汽车的主动安全性具有重要意义.在深入研究汽车操纵动力学和先进控制理论的基础上,设计了具有智能积分模块的模糊PID(Proportion-Integral-Dif-ferential)控制器,将该控制方法应用于DYC控制.建立了能够反映车辆转向工况基本动力学性质的车辆动力学模型,在Simulink环境下对开发的智能积分模糊PID控制器进行了仿真测试与分析.仿真结果验证了算法的可行性和有效性,表明智能积分模糊PID控制方法可以实现较为理想的DYC控制效果,在该领域具有良好的应用前景.Direct yaw-moment control （DYC） is a very important methodology of enhancing the vehicle stability, and its research is of great significance for improving the active safety of vehicle. Based on the indepth study of the vehicular handling dynamics and the advanced control theories, a fuzzy-PID controller with intelligent integral module was designed and applied for the DYC control. The vehicular dynamic model reflecting the basic dynamic characters of steering situation and the fuzzy-PID controller with intelligent integral module was established and simulated in the circumstance of Simulink. The simulation results validate the feasibility and effectiveness of this control algorithm, and indicate that it can realize perfect control of DYC. This control strategy is of a good prospect in this field.
