This paper investigates the influence of eddy
currents on the dynamic behavior of a novel hybrid-reluctanceforce
actuator for tip/tilt systems. The effects of eddy currents
on the mechatronic system dynamics are identified and modeled
by a first order system approximation. Their influence on the
achievable performance of a closed loop controlled system is
studied by investigating two configurations of the ferromagnetic
actuator yoke. An initial solid steel configuration of the yoke
is compared to a layered yoke structure with isolated steel
sheets, with the aim to improve the system bandwidth, which
is limited by the eddy currents. Robust PID feedback controllers
are designed for controlling the mover position of both
system configurations, resulting in comparable phase margins.
Experiments demonstrate that the closed loop bandwidth of
the prototype setup can be increased from 370 Hz to 1 kHz
by changing the yoke structure, which equals a bandwidth
improvement by a factor of 2.8.
