摘　　要：辅助动力装置常被抽取轴功率、空气质量流量用于发电、引气,为降低该过程对涡轮发动机造成的干扰,提升原控制系统的抗扰性能,研究了自抗扰控制方法及其参数化设计方法,以便在工程应用中能够根据线性化模型设计相应的控制参数,并在某型辅助动力装置模型上开展基于传统的增益调度PI控制方法与自抗扰控制方法的数值仿真验证。结果表明:自抗扰控制在保持与PI控制基本性能相似的前提下,具有更优的抗发电和引气干扰的能力,在干扰出现时能够更快速地恢复至原工作状态,转速波动量减少了35%,转速调节时间缩短了9%,具有良好的实际工程应用潜力。The auxiliary power unit is often used to extract shaft power and air flow for power generation and bleed.In order to reduce the interference caused by this process to the turbine engine and improve the anti-interference performance of the original control system,the active disturbance rejection control method and its parametric design method were studied,so as to design the corresponding control parameters according to the linearization model in engineering applications,and numerical simulation of a factory model based on the traditional gain scheduling PI control method and active disturbance rejection control(ADRC)method was conducted.Results showed that,on the premise of keeping the basic performance similar to that of PI control,ADRC had good anti-power generation interference and air entrainment interference performance,and can recover to the original working state faster when the interference occurred.More specifically,the speed fluctuation of ADRC was reduced by 35%,and the speed adjustment time was shortened by 9%,revealing the superior potential for practical engineering applications.
