This paper presents a method for controlling a deflection shape of a flexible beam by using shape memory alloy wires. The analytical solution for the deflection of the beam under the austenite transformation of the wires was obtained first, then a method for controlling the deflection shape was discussed on the basis of the genetic algorithm. Numerical calculations were carried out for some typical examples. It is clarified that the present system and the control method are applicable to the deflection control of flexible structures.
