Sensorless linear motor control addresses the market need for cost effective and more reliable control of electric motors by removing the mechanical sensors from the feedback control system. The mechanical sensors are the weakest link in the controlsystem in terms of reliability and parts and… More

Closed-loop control techniques such as those based on inner loop vector current control are well suited to meeting these performance criteria. However, they require flux or armature position knowledge which is usually based on the use of mechanicalfeedback sensors. Mechanical feedback sensors for… More

A "Small Buoy for Energy Harvesting" has applications for use on current and future buoy systems used by the submarine fleet of the United States Navy. This work proposes to meet the requirements by converting mechanical wave energy to electrical energy using a generation system housed in a spar… More

"Ocean Energy Extraction for Sensor Applications" has applications on buoy systems to be used by the United States Navy to increase situational awareness and battle-group integration by enabling power independent data acquisition and distributed sensor networks. Electro Standards Laboratories… More
