Abstract
In this paper, high precision motion control of piezo-actuated stage is discussed. In order to cope with the nonlinear characteristic of the piezoelectric actuator (PEA) and get high tracking performance, this paper proposes a new approach to design the discrete time sliding mode control (DSMC) with an ability to maintain the tracking error in a known region described by a performance function. The effectiveness of the proposed method is verified by experiments. The results show that the system not only performs well with complicated desired trajectories but also robust against external disturbances.
