摘要
在建立汽车车轮制动数学模型的基础上,针对汽车防抱制动系统,提出了一种基于生物免疫机理的免疫PID控制算法。与传统的PID控制及模糊控制算法进行仿真比较,结果表明免疫PID控制算法稳定时间短,系统输出的超调量小,响应时间少,制动距离短,优于传统PID和模糊控制算法,具有较高的应用价值。
Because the classic PID control doesn＇t satisfy the demand of automobile ABS in all conditions and it is short of an ability to identify road surface, fuzzy control is short of an ability to remove systemic stable error and it could not keep automobiles with higher control precisions. A dynamic mode of the wheels was built when an automobile was braking at first, aiming at automobile ABS and based on classic PID, a immune PID control algorithm was presented and used in automobile ABS system. Compared with the classic PID control algorithm and fuzzy control algorithm, the simulation result showed that the immune PID control algorithm has a shorter stabilization time, a smaller excess of system output, fewer response time and shorter braking distance, it is superior to the classic PID control algorithm and fuzzy control algorithm. The immune PID control algorithm has a higher application value.
