Adaptive sliding mode vibration control schemes for flexible structure system

This paper investigates the feasibility of adaptive feedforward sliding mode control and model reference adaptive sliding mode control scheme for the vibration suppression of a smart flexible beam. The adaptive least mean square (LMS) feedforward control with sliding mode controller and model reference adaptive control (MRAC) scheme with sliding mode controller are developed. Finite element model of flexible beam is calculated. Numerical simulations verified the desired performance of the adaptive sliding mode controllers and proved that the adaptive feedforward sliding mode control and model reference adaptive sliding mode control are effective approaches with application to vibration suppression problem .
