This paper addresses vibration control of a smart flexible cantilever sandwiched between a piezoelectric materials (PZT). A method of achieving self-sensing without bridge circuit are proposed in this study. Analysis of the system dynamics derives that the input-output relationship of a self-sensing system on the cantilever with PZT can be described by the state space expression with a direct transmission part. Controller design of the proposed self-sensing system is considered in this paper. Calculated simulations are performed to evaluate the performance of the designed controller via uncertainty by supposing a direct transmission part variation. Simulation results demonstrate that H_∞ optimal controller can be achieved to compensate of the robust stability for self-sensing system under a direct transmission part with uncertainties.
