摘　　要：针对车载自动调平装置快速性和高精度的要求,采用"以面调面"追逐最高支撑点的调平策略。执行机构内环采用模糊PID同传统PID相结合的PID控制器,外环采用PD控制器进行同步控制,同步误差经PD控制器对从动执行元件进行补偿,从而保证了调平的高精度及快速性。试验结果表明:该调平装置调平时间减少了29 s,调平精度在3.4'以内。Aiming at the requirement of fast response and high precision in automatic vehicle leveling device,the leveling strategy of chasing the highest anchor on surface adjusted to surface is employed. The fuzzy PID combining with the traditional PID is used as the inner controller and the PD controller is used as the outer controller to synchronically control the actuator,in which the synchronization error is compensated to the slave actuator by PD controller to ensure the high-precision and fast response. The experiments show that and the leveling time can be reduce to 29 s and the leveling precision is less than 3.4 points. Thus the leveling strategy and control algorithm have the significance in engineering application.
