Distributed Control System For Parallel-Connected Dc Boost Converters, Steven Goldsmith Aug 2017

Distributed Control System For Parallel-Connected Dc Boost Converters, Steven Goldsmith

Michigan Tech Patents

The disclosed invention is a distributed control system for operating a DC bus fed by disparate DC power sources that service a known or unknown load. The voltage sources vary in v-i characteristics and have time-varying, maximum supply capacities. Each source is connected to the bus via a boost converter, which may have different dynamic characteristics and power transfer capacities, but are controlled through PWM. The invention tracks the time-varying power sources and apportions their power contribution while maintaining the DC bus voltage within the specifications. A central digital controller solves the steady-state system for the optimal duty cycle settings ...


It's No Accident: Evaluating The Effectiveness Of Vehicle Safety Inspections, Alex Hoagland, Trevor Woolley May 2017

It's No Accident: Evaluating The Effectiveness Of Vehicle Safety Inspections, Alex Hoagland, Trevor Woolley

FHSS Mentored Research Conference

Traffic fatalities have fallen steadily over the past two decades, particularly those due to car failure. Many have attributed this fall to safer vehicle technology. This trend has led many states to reevaluate mandatory vehicle safety inspection programs. This study sought to answer the question, does the elimination of vehicle safety inspections have an effect on traffic fatalities?

Michigan Tech Patents

A wire neutralizing system for use with a vehicle including a frame adapted to be hitched to a vehicle. At least one wheel supports the frame while a bottom of the wheel rolls over terrain having buried wires. The system also includes a blade movable between a stowed position in which the blade is above the bottom of the wheel and a deployed position in which the blade is below the bottom of the wheel, such that the blade plows through the terrain to disable buried wires when in the deployed position.
