Abstract:
A new model identification method of hydraulic flight simulator adopting improved particle swarm optimization (PSO) and wavelet analysis is proposed for achieving higher identification precision.Input-output data of hydraulic flight simulator were decomposed by wavelet multiresolution to get the information of different frequency bands.The reconstructed input-output data were used to build the model of hydraulic flight simulator with improved particle swarm optimization with mutation (IPSOM) to avoid the premature convergence of traditional optimization techniques effectively.Simulation results show that the proposed method is more precise than traditional system identification methods in operating frequency bands because of the consideration of design index of control system for identification.
Key words: hydraulic flight simulator wavelet analysis multiresolution analysis (MRA) particle swarm optimization (PSO) frequency bands weighting approach
