Abstract
This work deals with the extend time delay feedback control of an SMA-pendulum system. The SMA elements are used to control the system’s dynamics been in two different ways: as ideal actuators and as constrained actuators. The energy equation is used to model the constrained actuator and the differences between the ideal control and constrained control are analyzed by the Floquet exponents of the stabilized UPO. The influence of the errors on the Floquet exponents themselves is performed by varying the convection coefficient on the SMA elements. Results show that the control of the period 1 and period 2 UPO are possible within a certain limit of restrictions.
