Multi-Variable Self-Tuning Control for Aero-Engines

Based on the least square estimation with forgetting factor μ,the multi-variable self-tuning control was proposed for aero-engines with strong nonlinearity.The control parameters were obtained from estimation directly.The closed-loop control system was identifiable through the analysis.The simulation results show that the system features the rapid response,the high precision and the ability to restrain disturbance and coupling and the estimated parameters converge quickly.
