摘　　要：为了保证滑模成型后水泥混凝土路面的初始平整度,通过理论分析滑模摊铺机自动找平系统的数学模型,并在MATLAB软件中的Simulink界面下分别创建引入普通的PID控制器和模糊自适应PID控制器的摊铺机的自动找平系统的仿真模型并进行仿真分析。结果表明:引入模糊自适应PID控制改进后的系统较普通PID在响应速度和动态品质方面的控制效果都有很大的提升,即改进后的自动找平系统更能保证路面滑模施工的平整度。In order to ensure initial smoothness of cement concrete pavement after forming sliding mode, theoretical analysed mathematical model of slipform paver automatic leveling system is obtained and a simulation model of the automatic leveling system of slip-form paver is constructed based on normal PID controller and fuzzy adaptive PID control under the SIMULINK interface in MATLAB software. Besides, the simulation analysis is also carried out in this paper. The result shows that the effect of fuzzy adaptive PID control is better than that of normal PID control, so the automatic leveling system can ensure the smoothness of pavement more reliably after improving it.
