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.
