摘　　要：为了保证沥青砂浆车内部计量仪器对水平度的要求和满足频繁移动的特点，建立了沥青砂浆车调平系统模型，分析和研究了不同的调平控制算法，最后通过实验对不同的调平控制算法进行了实验对比研究。研究结果表明：在调平精度为±0．2°以上时，单方向调平控制算法调平容易出现不收敛和调平效率低下；在满足调平精度为±0．1°的前提下，去耦合最低点调平控制算法能保证调平收敛和提高调平效率。基于去耦合最低点调平算法能满足移动式沥青砂浆车调平精度和调平效率。In order to ensure levelness of measuring instrument in the asphalt mortar vehicle and satisfy the features of mobile often. A module of leveling system for asphalt mortar vehicle was established. The different leveling control algorithms were analyzed and studied. The different leveling control algorithms were compared and studied by a lot of tests. The results showed that single direction angle leveling algorithm would lead to non-convergence and low leveling efficiency as leveling accuracy of asphalt mortar vehicle is above ±0.2°. The lowest point leveling control algorithm removed couple can ensure leveling convergence and a high leveling efficiency when leveling accuracy is ±0.1°. The leveling control algorithms based on the lowest point can satisfied the leveling accuracy and efficiency of mobile asphalt mortar vehicle.
