摘　　要：针对单陷波补偿算法滤波带宽较窄的问题,提出将双陷波补偿算法应用于单谐振点发动机伺服机构控制并建立了数学模型。仿真结果表明,双陷波补偿算法能够在较宽范围内相对有效地抑制谐振峰,且其低频段相角与单陷波补偿算法相比滞后并不明显。为验证分析的正确性,在试验台上对伺服机构进行陷波补偿算法试验,为双陷波补偿算法在火箭推力矢量控制中的扩展应用奠定基础。Aiming at the problem of single-notch with narrow bandwidth, a double-notch compensation algorithm was applied to the servo-mechanism of single resonance engine. The mathematical model of the double-notch filter was established. Simulation results showed that the resonance peak was effectively inhibited, and the phase delay was improved compared to the single-notch filter. Experiments on notch compensation algorithm were carried out at test rig to verify the simulation model, and laid the foundation for the application of double-notch compensation algorithm on rocket thrust vector control.
