摘要
电液伺服加载系统就是用以模拟飞行器在飞行过程中舵面所受空气动力(力矩)载荷谱,完成舵机的带载试验。首先对电液伺服加载系统进行了数学建模;其次根据静态加载和动态加载的特点,分别提出了加载系统的积分分离PID和抗积分饱和PID控制算法。在此基础上,开发了电液伺服加载系统,并进行了被试舵机的加载试验。试验测试表明,所研制的电液加载伺服系统能够满足加载控制系统的要求,有效降低系统响应的多余力,获得了良好的试验效果。
The electro-hydraulic servo loading system is used to simulate the aerodynamic （torque） load spectrum suffered by the aircraft rudder in the flight and can complete the loading experiments of actuator under laboratory conditions. Firstly, a mathematical model for the electro-hydraulic servo loading system is built. Secondly, according to the characteristics of static loading and dynamic loading , the control algorithm, the integral separation PID and the anti-integration saturation PID are presented, respectively. On the basis servo loading system is developed and loading experiments are completed. Good And the results show that the requirements of loading control system can be met servo loading system, and the extraneous force can be reduced. of the above, the electro-hydraulic experimental results are achieved. by the designed electro-hydraulic
