摘要
针对高超声速飞行器发汗冷却系统的温度控制问题,在一维固定边界发汗冷却模型的基础上,提出了用于调节飞行器壁面多孔介质温度的自抗扰控制器,并进行了数值仿真。该控制器不依赖于多孔介质温度场精确的数学模型,通过从系统的输入输出数据中提取干扰信息并进行补偿,实现对热流干扰的抑制。仿真结果表明,针对发汗冷却系统设计的自抗扰控制器,能够实现对参考温度的快速跟踪;且相较于传统的PID控制,温度响应没有超调;在有外界热流干扰时,具有较强的鲁棒性和适应性,可以为发汗冷却控制系统的工程应用提供一定参考。
Aiming at the temperature control problem of the hypersonic vehicle transpiration cooling system,this paper proposes an active disturbance rejection controller(ADRC)to adjust the temperature of the porous medium on the vehicle wall based on the one-dimensional fixed boundary sweating cooling model,whose effectiveness and advantages are verified by a numerical simulation.The controller does not rely on the precise mathematical model of the temperature field of the porous medium.The heat flow disturbance is suppressed by extracting and compensating disturbance information from the input and output data of the system.The simulation results show that the ADRC designed for the transpiration cooling system can quickly track the reference temperature.Compared with the traditional PID control,the temperature response under ADRC has no overshoot.In addition,when external heat flow interference occurs,the ADRC has strong robustness and adaptability,which can provide a certain reference for the engineering application of transpiration cooling control systems.
