Abstract: This paper investigates the design of an iteration-based controller combined with feedback control to address the positioning error caused by hysteresis in a shape memory alloy (SMA) actuator. ...

Abstract: This paper studies repetitive control (RC) with linear phase lead compensation to precisely track periodic trajectories in piezo-based scanning probe microscopes (SPMs). Quite often, the lateral ...

Abstract: The development of manufacturing tools and processes capable of precisely positioning and manipulating nanoscale components and materials is still in its embryonic stage. Microactuators are emerging ...

Abstract: Control can enable high-bandwidth nanopositioning needed to increase the operating speed of scanning probe microscopes (SPMs). High-speed SPMs can substantially impact the throughput of a wide ...
