To solve this problem, the use of low-cost and compact components in stages is investigated. Earlier research done in the MSD group already showed that relatively low-cost sensor concepts and mechanical designs can be applied to significantly reduce the price of stages, while still achieving sub-micrometer precision. In this research, the applicability of the Arduino Due micro-controller (€40) and amplifiers based on Pulse Width Modulation (PWM, €6) in precision stages is investigated. The use ofcheap components doesn’t come without its drawbacks. To name a few examples, the Analog-to-Digital Converter (ADC) in the Arduino doesn’t have the resolution of higher quality components, PWM adds frequency content to the output of the amplifier and the Arduino processor isn’t as fast. In this research project, an extensive theoretical analysis is done to reveal how the components affect the overall performance of the stage, which can then be used to optimize system parameters to circumvent the performance losses that are inevitable with cheap components. This way much of the overall system performance canbe maintained. The theory is experimentally validated and the Arduino and PWM based amplifiers are successfully implemented into a working prototype with a precision of 1.5μm.
