Electro-hydraulic servo system of stick supporting mechanism which was used to simulate the attack angle mechanism in wind tunnel was set up. The compound control strategy with speed feedforward and position feedback was presented. The speed feed-forward model was deduced. And the reasonable speed and position signals were designed,by which the undisturbed switching of the speed feedforward control and the position feedback control was realized. The hydromechatronic model of electro-hydraulic servo system of stick supporting mechanism was established by co-simulation technology with AMESim and Motion. The simulation and experimental results conform to theoretical analysis and it is shown that the position and speed of the cylinder can be controlled simultaneously with the technology of speed and position hybrid control.%搭建了模拟风洞迎角机构的杆支撑机构电液伺服系统。采用速度前馈和位置反馈复合控制策略，推导了速度前馈计算模型，通过合理设计速度位移曲线，实现了速度前馈控制和位置反馈控制的无扰切换。利用AMESim/Motion联合仿真技术，创建了杆支撑机构电液伺服系统的机、电、液仿真模型。理论推导、仿真研究与试验结果相互印证，证实了速度前馈和位置反馈复合控制策略的有效性，可以实现油缸位置和速度的同时精确控制。
