Method for identifying wall surface pressure parameters of whole flow channel of scramjet engine

The invention discloses a scramjet engine full-flow-channel wall surface pressure parameter identification method. The method comprises the steps that a relevant data set of full-flow-channel wall surface pressure is obtained; utilizing the training set to construct an agent model of uncertain propagation of the parameters of the full-flow-channel turbulence model; obtaining a plurality of identification models and optimal parameters according to the agent model, the Bayesian theory and the particle swarm algorithm; obtaining related pressure data corresponding to the current identification model by using numerical simulation software; according to the related pressure data and the pressure data obtained by a real test, error variation is obtained; judging whether the error variation exceeds a preset threshold value or not, judging whether the current identification model is the last identification model or not, and performing nesting and fusion processing on all the identification models; performing paramete
