为解决汽车自动转向控制系统的死区问题,采用混合逻辑建立含死区特性的混合逻辑动态汽车操纵模型,并通过预测控制方法进行优化控制.混合逻辑动态建模引入的逻辑变量考虑了各个区间,从而确定了系统的动态方程.模型预测控制通过预测输出、滚动优化、反馈校正环节,能够获得较好的控制效果和鲁棒性.研究结果表明:混合逻辑动态汽车操纵模型能够获得较好的控制效果,基本不存在稳态误差.该研究成果对提高汽车行驶安全性和平稳性有一定的理论指导作用.
In order to solve the problem of dead zone of auto steering control system, hybrid logic is used to establish a hybrid logic dynamic vehicle control model with dead zone characteristics and optimized control by predictive control method. Logical variables introduced by hybrid logic dynamic modeling consider each interval , So as to determine the dynamic equation of the system.Model predictive control can get better control effect and robustness through predictive output, rolling optimization and feedback correction.The results show that hybrid logic dynamic vehicle control model can get better Control effect, there is basically no steady-state error.The research results to improve the safety and stability of the car has a certain theoretical guidance.
