Aeroengine deviation parameters nonlinear estimation using improved Quantum-behaved PSO algorithm

Estimation of aeroengine deviation parameters (EDPs) is one of the key technologies of performance seeking control (PSC). The estimation errors may be great using traditional linear estimation algorithm, so nonlinear estimation model is established. The problem of nonlinear estimation is conversed to a problem of optimization. Mutation Quantum-behaved PSO (QPSO) algorithm is used to estimate EDPs. Take the given turbofan engine as an example, the feasibility of using Mutation QPSO (MQPSO) to estimate EDPs is validated by simulation.
