摘要:
为了实现对摊铺机模拟试验台行驶速度的精确控制,根据试验台活动路面的具体功能要求,采用电液控制技术,以可编程控制器为核心,完成了活动路面板的行驶系统的液压和控制系统设计.对泵控马达的调速形式进行了分析,通过控制器调节PWM信号的占空比来改变泵的排量从而改变马达转速.采用斜坡控制完成活动路面板行驶速度的过渡,避免了活动路面板由于起步或者急剧改变其行驶速度时产生的冲击.采用PID算法实现对活动路面板的恒速控制.
Abstract:
In order to control the traveling speed of the paver experimental bench accurately,according to thespecific function requirement of the mobile road slab of the experimental bench，the design of the hydraulicsystem and control system of the mobile road slab is accomplished by means of adopting electro-hydraulic con-trol technology and using PLC. The pump-control-motor control method is introduced.The motor speed varieswith the pump discharge when the duty ratio of the PWM signal controlled by the controller changes. Thespeed of the mobile road slab changes according to a slope function,which avoids the impact when the mobileroad slab starts to move or its speed is sharply changed. The constant - speed control of the mobile road slab isaccomplished by adopting PID algorithm.
