Terminal Sliding Tracking Control of Piezoelectric Actuators

Article Preview

Abstract:

There are parametric uncertainties, nonlinearities including the hysteresis effect, and other un-modeled disturbances existing in piezoelectric actuator systems. A terminal sliding mode control methodology is proposed in this paper. By using nonlinear TSM manifold, the system errors can converge to zero in finite time. So high-precision tracking performance can be achieved. Simulation results are presented to validate the design.
