Findings on Nanopositioning Reported by Investigators at University of Nevada

June 20, 2014

By a News Reporter-Staff News Editor at Science Letter -- Current study results on Nanopositioning have been published. According to news originating from Reno, Nevada, by NewsRx correspondents, research stated, "A novel dual-stage nanopositioner control framework is presented that considers range constraints. Dual-stage nanopositioners are becoming increasingly popular in applications such as scanning probe microscopy due to their unique ability to achieve long-range and high-speed operation."

Our news journalists obtained a quote from the research from the University of Nevada, "The proposed control approach addresses the issue that some precision positioning trajectories are not achievable through existing control schemes. Specifically, short-range, low-speed inputs are typically diverted to the long-range actuator, which coincidentally has lower positioning resolution. This approach then limits the dual-stage nanopositioner's ability to achieve the required positioning resolution that is needed in applications where range and frequency are not inversely correlated (which is a typical, but not always the correct assumption for dual stage systems). The proposed range-based control approach is proposed to overcome the limitations of existing control methods."

According to the news editors, the research concluded: "Experimental results show that the proposed control strategy is effective."
