Optimisation of Engine Vibration Control Based on Particle Swarm Algorithm
Based on the central composite design in response surface design,combined with the QAR data,a function model of engine N1 vibration value with respect to fuel flow rate,VBV angle,and VSV actuator cylinder position is fitted,and the particle swarm optimization algorithm is used to optimize the function model,so that the matching effect of the engine related parameters is more effective,and the engine vibration value is reduced to a very desirable level,compared with that after the optimization of the QAR data and the response surface method.ideal level.
