摘要
针对工程机械定速比传动的特点，提出一种交流双机定速比传动自适应控制方法．控制器由一个比例反馈控制器和前馈自适应补偿器组成，构成一个定速比跟踪自适应复合控制系统．按Ｐｏｐｏｖ超稳定判据确定比例控制增益和自适应控制律系数，利用优化方法寻求最佳值．通过仿真验证了这种定速比自适应控制方法的有效性．
This paper presents an adaptive control algorithm of dual AC motor drives according to thecharacteristics of the fixed velocity ratio drives in engineering machinery. The controller consists of a proportional feedback controller and an adaptive feedforward compensator,and a complex control system offixed velocity ratio tracking is constituted. The proportional control gain and the coefficients of the adaptivelaws are determined by means of the Popov hyperstable theory,and their optimum values are gotten by optimization. The effectiveness of the adaptive fixed velocity ratio control algorithm is demonstrated by simulation.
