摘　　要：针对航空轴承试验机力加载电液伺服系统动态响应较差的问题,采用内模控制策略对其进行系统优化,用以提升系统的响应速度,改善系统的动态特性。通过构建力加载控制系统数学模型,分析研究系统特性,综合考虑液压固有频率的影响因素确定了模型的参数,进而基于此模型设计了内模控制器。为验证内模控制器的控制效果,对其进行仿真和试验分析。仿真和试验研究结果表明,相较于PID控制算法,内模控制算法可以有效改善力加载控制系统的响应速度和跟踪精度,并提高系统的抗干扰性和鲁棒性。Aiming at the problem of poor dynamic response of electro-hydraulic servo system under force loading of aircraft bearing testing machine,the internal model control strategy was used to optimize the system to improve the response speed and dynamic characteristics of the system.By building a mathematical model of the force loading control system,analyzing and studying the system characteristics,the parameters of the model were determined by considering the influencing factors of hydraulic natural frequency,and then the internal model controller was designed based on the model.In order to verify the control effect of the internal model controller,simulation and experimental analysis were carried out.Simulation and experimental results show that,compared with PID control algorithm,the IMC algorithm can effectively improve the response speed and tracking accuracy of the force loading control system,and improve the anti-interference and robustness of the system.
