Abstract: During the take-off and landing transition stage of the vertical/short takeoff and landing (V/STOL) aircraft, there is a pow-er system conversion process. In order to solve the problem that the control variables are coupled and redundant in the conversion process, the corresponding inner loop stability augmentation controller and control allocation strategy were designed.The power system model and dynamic model with lift loss were established by using the empirical formula of jet effect.Based on the conventional nonlinear dynamic inverse control of the outer loop, L1 adaptive controller was designed as the inner loop stability augmentation control to compensate the mismatch and uncertainty in the system.A control allo-cation strategy was designed based on efficiency allocation criteria to solve the problem of actuator deflect allocation.The performance and robustness of the controller were verified by inner loop simulation and Monte Carlo shooting. The simu-lation results show that the controller can track the reference input well even with large parameter perturbation, and has good robustness.
