The test and control system based on 32-bit fixed-point DSP TMS320F2812 is designed for the morphing wing with the SMA actuators.A method for testing and controlling deflection angle of the wing is presented.Through hardware and software design

combined with the exploiting and debugging environment of DSP

the experiment for controlling the deflection angle of the single joint of the morphing wing is completed.The results of the experiment show that a good control effect is obtained

and can meet the basic requirement.This research will also provide a reliable basis for the precise control of the overall structure of the morphing wing in the future.
