چکیده

s-Fixed controllers can become even unstable, with large changes in system parameters. This problem can be avoided using robust control and adaptive control design techniques. To obtain robust performance, it is desirable that the closed loop poles of the perturbed structure remain at prespecified locations for a range of system parameters. In the present study, the controllers based on adaptive and robust pole placement method are implemented on smart structures. It was observed that, adaptive pole placement controllers are noise tolerant but require high actuator voltages to maintain stability. However, robust pole placement controllers require comparatively small amplitude of control voltage to maintain stability, but are noise sensitive.
