摘　　要：针对航空发动机高空模拟试验对进气环境压力模拟控制系统所提出的高精度、强抗扰性、强鲁棒性的迫切需求,提出一种线性/非线性自抗扰控制切换控制策略。首先,分析了高空舱进气环境压力模拟控制系统的技术难点并基于高空舱环境模拟进气系统的基本结构,推导出其数学模型以及建立仿真试验平台;随后,分析了线性自抗扰控制和非线性自抗扰控制各自的优缺点,进而设计了线性/非线性自抗扰切换控制策略;最后,在仿真平台上验证了线性/非线性自抗扰切换控制策略,并与单独采用线性自抗扰控制或非线性自抗扰控制进行了对比分析。结果表明,线性/非线性自抗扰切换控制器兼具线性与非线性自抗扰的优势,能够根据任务工况实时切换合适的自抗扰控制器,进一步提升进气环境模拟控制系统的抗扰能力、调节时间与控制精度,具有较高的工程应用价值和前景。Addressing the critical demands for high precision,strong disturbance resistance,and robustness required by the air intake environment pressure simulation control system across aero engine high-altitude simulation tests,a linear/nonlinear active disturbance rejection control(ADRC)switching strategy(SADRC)was proposed.Initially,technical complexities of the air intake environment simulation control system was analyzed,and the mathematical model was derived based on the basic structure of the environmental simulation air intake system of high altitude cabin,and the simulation test platform was established.Subsequently,the merits and demerits of linear ADRC(LADRC)and nonlinear ADRC(NLADRC)were evaluated,leading to the formulation of a hybrid linear/nonlinear ADRC switching strategy.Finally,SADRC was verified on the simulation platform and compared and analyzed with the linear or nonlinear ADRC.The results indicate that the SADRC amalgamates the strengths of both linear and nonlinear approaches,which can switch the appropriate controller in real time according to the task conditions,substantially enhance disturbance rejection capabilities,response time,and control accuracy.This underscores its strong engineering application and prospect.
