Kurzfassung englisch:
This paper introduces an advanced phase-lockedloop
(PLL) control structure for an electromagnetically actuated
fast steering mirror (FSM). It enables a performance
improvement when tracking Lissajous trajectories on a modified
FSM. The dynamics of the FSM are inserted into the
phase control loop of the PLL control structure, such that
frequency and phase of the output and the reference signal are
synchronized. Feedforward gains are used to enable matching
of the output and reference scan amplitudes. It is shown
that the PLL together with decoupling control blocks is also
capable of compensating crosstalk between the FSM axes.
The performance of the designed control system is compared
to state of the art dual tone (DT) controllers for Lissajous
trajectories. While both control structures show comparable
current consumption, the resulting rms tracking error can be
reduced by 60% when using the proposed PLL-based controls.
