摘要:
从涡桨发动机的工作原理、特点和全权限数字发动机和螺旋桨控制(FADEPC)设计要求出发,分析了等涡轮前总温调节、等转速调节、等螺旋桨功率调节的单变量调节方法以及通过调节燃油流量保持涡轮前总温不变或保持螺旋桨功率不变、通过调节桨叶安装角保持转速不变的双变量调节方法。在此基础上,根据涡桨发动机工作特点,并从控制的可实现性角度考虑,提出了一种螺桨发动机在全飞行包线范围内按等螺旋桨功率、等转速和等涡轮后总温调节、按功率限制设计高度切换的开环+闭环结构式分段调度双变量组合控制的方法。在3种不同的飞行速度条件下,仿真验证了所述控制方法的可行性,转速最大相对误差不超过0.1%。
Abstract:Starting from the working principle and characteristics of turboprop engine and the design requirements of full authority digital engine and propeller control (FADEPC), the univariate regulation methods of equal turbine front total temperature regulation, equal rotor speed regulation and equal propeller power regulation, as well as the bivariate regulation methods of keeping the total turbine front temperature unchanged or propeller power unchanged by adjusting the fuel flow, and keeping the rotor speed unchanged by adjusting the blade installation angle were analyzed. According to the working characteristics of turboprop engine and from the perspective of control realizability, an open-loop + closed-loop structured piecewise scheduling bivariate combined control method was proposed, in which the propeller engine was adjusted according to equal propeller power, equal rotor speed and equal total temperature behind the turbine within the whole flight envelope, and switched according to the power limit height designed. The feasibility of the control method was verified by simulation under three different flight speeds, and the maximum relative error of rotating speed was 0.1%.
