Abstract: A multiplying nonlinear model was built to the electro-hydraulic compound control of airborne actuation system. A new approach based on feedback linearization and receding horizon optimization was presented to the system. The relative degree was less than the order of the system, so nonlinear system was transformed into a linear subsystem and a part of nonlinear via feedback linearization. The zero dynamics was researched so that the stability of the control system was guaranteed. On-line adjustment based on receding horizon optimization to the global linear model had strong robustness to unmodelled dynamic as well to enhance dynamic response. A finite-time horizon linear quadratic optimal servo problem was formulated with penalty on time-derivative of the control input as well as the error of trajectory in the performance index. State feedback was employed to keep the whole system stability. Simulation results show that the approach can eliminate uncertainty and disturbance and increase robustness. The system has better dynamic performance.
