摘要
在不破坏沥青路用性能的前提下,为优化管路沥青的加热动态响应性,设计了管道循环加热控制系统。并采用最优线性二次型方法为沥青循环流动的管道加热系统建立了数学模型,将最优线性二次型PID温控法与传统的PID温控法进行了分析与对比。结果表明,前者加热时温度的超调量明显小于后者,加热到目标温度所需要的时间也明显更短。可知,最优线性二次型PID温控法可以大大减少PID参数整定时间,其加热效率更高更节能,能很好地满足循环加热系统控制需要。
To optimize the dynamic responsiveness of the heating bitumen in the pipeline and avoid decreasing the bitumen performance,the circulate pipeline heating system is designed.The mathematic model of the bitumen pipeline heating system is built based on the optimum linear quadric method.By analyzing the results of normal PID method and linear quadric PID method,it is very obvious that the overshoot of the optimum linear quadric method is remarkable smaller,and the adjusting time is much shorter.The optimum linear quadric method can increase the parameter setting efficiency greatly.And it is more heat efficient and energy-saving.The method performs quite well for the circulate pipeline heating system.
