Abstract：The design continuously variable-camber wings integrating SMA flexible structures represented a crucial development direction for future morphing wings.To address complex flight environments deformation requirements，wings should possess multi-camber deformation adjustment capabilities precise control performance. A variable-camber wing structure was presented driven by a threestage SMA wire actuator combined with modular flexible components，along with a multi-state deformation fuzzy control algorithm.First，by an open-loop test，the control logic was established based on minimum energy consumption heating stages. Subsequently，a multi-stage fuzzy PID control algorithm Was developed to hle SMA nonlinear driving characteristics uncertain factors like load variations， ensuring precise deformation control across diferent camber states.Experimental results demonstrate that the proposed multi-state fuzzy control algorithm may efectively achieve precise deformation control under various variable curvature states. Compared with conventional PID control，the new control algorithm significantly reduces seting time， effctively improves both mean absolute errors maximum overshoots， while maintaining good robustness.
