摘　　要：文章介绍某加载装置组成及工作原理,建立加载装置电液控制模型,开展加载装置比例积分控制(PI)、速度前馈补偿控制、自适应反步控制策略分析,并对以上控制策略进行验证,验证结果与分析情况一致。采用速度前馈补偿控制可以弥补比例积分控制策略中加速度因素导致的力加载控制偏差;采用自适应反步控制可进一步改善系统参数不确定性导致的控制偏差。The composition and working principle of a certain loading device is introduced,an electro-hydraulic control model of the loading device is established.The proportional integral(PI)control,speed feedforward compensation control,and adaptive backstepping control strategy of the loading device are analyzed,and the above control strategies are verified.The verification results are consistent with the analysis situation.The use of speed feedforward compensation control can compensate for the force loading control deviation caused by acceleration factors in the proportional integral control strategy.The use of adaptive backstepping control can further improve the control deviation caused by system parameter uncertainty.
