Summary:In order to test aircraft actuators moving aerodynamic control surfaces, it becomes more and more important to have flexible facilities which are able to produce a variety of loading conditions with a given accuracy. The so-called Modular Iron Bird (MIB), which is now in the design phase, will be able to reproduce aerodynamic and inertial loads for a large category of aircraft. The MIB control system has to guarantee the application of a desired time history of forces through a hydraulic system, while the aircraft actuator is driven in closed-loop to guarantee a given aerodynamic surface deflection. Therefore, two controllers are fighting each other, and this makes the control problem challenging. In this paper, a nonlinear model-based predictive control strategy is proposed. Numerical results allow to test the effectiveness of this control strategy and its benefit with respect to the classical PID approach.
