Embodiment Construction
[0038] The technical solution of the present invention will be described in detail below through a preferred embodiment in conjunction with the accompanying drawings:
[0039] Such as figure 1 As shown, the variable rotor speed helicopter-turboshaft engine integrated control device in this embodiment is composed of three parts: the helicopter rotor prediction model, the turboshaft engine prediction model, and the online optimization unit. Both the turboshaft engine prediction model and the helicopter rotor prediction model are obtained offline. Depend on figure 1 It can be seen that within a single simulation step, the turboshaft engine predictive model and the helicopter rotor predictive model predict the output in the future according to the input respectively online, and transmit it to the nonlinear model predictive controller (that is, the online optimization unit). The Sequential Quadratic Programming (SQP) algorithm solves the objective function online, outputs the fue...
