This paper addresses the issue of stabilizing a morphing aircraft within a finite timeframe while undergoing morphing maneuvers. To enhance control performance during the morphing process, the sliding mode controllers are designed for the longitudinal direction. First, the longitudinal nonlinear dynamic model is performed. Second, adaptive dual-layer algorithms are implemented to enhance the anti-interference. These algorithms consist of inner and outer layers, where the outer layer corresponds to the sliding mode gain, and the inner layer adjusts the rate of change of the outer layer parameters. Last, comparison results show that the proposed controllers have smaller error.
