中文摘要:
      等效系统拟配是一种有效评价高阶电传操纵飞机飞行品质的方法。传统的等效拟配通常采用最小二乘等方法,拟配结果易受初值选取的影响。建立了综合考虑某型飞机本体动力学、电传操纵系统、驾驶员操纵和升降舵的人 机闭环系统模型。给出了一种基于自适应克隆选择算法的等效系统拟配流程。采用自适应克隆选择算法对该高阶的人 机闭环系统进行了低阶等效拟配,拟配精度满足失配包络线的要求。仿真结果表明自适应克隆选择算法具备较强的寻优能力,可有效提高拟配精度。
英文摘要:
      Equivalent system simulation is a method to effectively evaluate the flight quality of high order fly by wire aircraft. The traditional equivalent matching usually adopts the method of least squares, and the matching result is susceptible to the selection of the initial value. Firstly, a closed loop pilot aircraft system model , in consideration of the dynamics of a certain aircraft, the fly by wire system, the pilots manipulation and elevator,is established, and then an equivalent system matching process based on adaptive clonal selection algorithm is presented.Finally, the closed loop high order pilot aircraft system is adopted by the adaptive clonal selection algorithm. A low-order equivalent fit is performed, and the accuracy of the fit meets the requirements of the adaptive envelope. The simulation results show that the adaptive clonal selection algorithm has strong ability to optimize, and can be used to effectively improve the accuracy of the proposed matching.
