Parameter adjusting method and system suitable for composite stability control system

The invention provides a parameter adjusting method and system suitable for a composite stability control system, wherein the method comprises the following steps: S1, sequentially disconnecting a stability augmentation loop and an overload loop from a rudder control part, analyzing the open-loop characteristics of the composite stability control system, and reversely solving the parameters of the composite stability control system through the open-loop parameter set values of the stability augmentation loop and the overload loop; and S2, carrying out optimization design on open-loop parameters of the stability augmentation loop and the overload loop by adopting a particle swarm algorithm. The parameter adjusting method for the composite stability control system starts from the open-loop index of the composite stability control system, and is more beneficial to understanding the stability of the system. A particle swarm optimization algorithm is adopted to optimize open-loop indexes of the stability augmentat
