Vergleich der Scan-Performance bei Nanopositioniersystemen mit großem Bewegungsbereich

Abstract: Zusammenfassung: In der vorliegenden Arbeit werden zwei Nanopositioniersysteme in Bezug auf ihre Positioniergenauigkeit während der Bewegung verglichen. Beide Systeme besitzen einen planaren Bewegungsbereich von ≥ 100 mm, werden durch Linearmotoren angetrieben und die Position wird durch Laserinterferometer gemessen. Groẞe Unterschiede existieren jedoch im mechanischen Aufbau. Das erste Positioniersystem ist ein zweiachsiger Demonstrator dessen zwei Läufer auf Wälzkörpern gelagert sind. Dies führt zu dem Probl… Show more

“…The drive forces of the three linear actuators act simultaneously on the slider. The 120 • arrangement allows a resulting force in any direction within the x-y plane and additionally a rotation around the z axis can be generated [24]. Accordingly, this results in a circular range of motion.…”

“…where α W = −30 • and α V = −150 • are the rotation angles of the V and W axis starting from x axis. The core of the control system is formed by three separate classic PID controllers for each of these coordinates [24]. For (x, y, ϕ z ) T , an independent PID controller in its standard form is employed:…”

“…Über den gesamten Bereich erreichen NPMMs eine 3D-Messunsicherheit von weniger als 10 nm. Die hohe Ortsauflösung von 80 pm wird durch stabilisierte interferometrische Messsysteme erreicht [18]. In Kombination mit adäquaten optischen oder taktilen Oberflächensensoren werden hochpräzise Struktur-und Oberflächenmessungen im Nanometerbereich ermöglicht.…”

“…Besides the rather conventional spatial filtering of single partial waves by means of amplitudes or phase masks, a manipulation of the exposure wave front may lead to novel, flexibly adjustable interference pattern distributions. obtained in the evaluation of control algorithms by means of field programmable gate array (FPGA) platforms have been promising [81].…”

“…An example of a magn etic vertical actuator guide including weight force compensation is shown in figure 8. Thus, it was possible to achieve a highprecision and fast control of paths of up to 6 mm s −1 [81] on the basis of laser focus probes and laser interferometers [106]. The efficiency of the control systems designed for this purpose was also demonstrated [81,107].…”
