Abstract

Control schemes for nanopositioners typically combine damping and tracking. Due to the positioning performance requirements of the nanopositioning system, it is desirable for the closed-loop frequency response of the nanopositioner to mimic ripple-free pass-band low-pass characteristics. Earlier reports are available on simultaneous damping and tracking control emulating a Butterworth filter design, but this technique only incorporates a single integrator for tracking, which is inadequate for error-free tracking of the triangular and ramp-like signals typically used as input to nanopositioning systems. Double integral tracking guarantees error-free tracking, but is difficult to implement due to phase-related stability issues. In this work, a dual-loop integral tracking algorithm is proposed. Using simulation, it is shown that in the presence of hysteresis, the proposed dual-loop scheme delivers a more accurate positioning performance than the traditional single-loop integral tracking strategy.
