A double-spring-mass physical model is proposed for double-resonance-frequency engines in launch vehicles. The characteristic parameters are identified and the corresponding mathematical model for servo-mechanisms is derived. The optimization of servo-mechanism’s control algorithm is studied using a direct numerical optimization method. Then, simulation analysis and trial experiments are completed. The result shows that double-notch filter is a more acceptable compensation method.
