Simulation based evaluation of a nonlinear model predictive controller for friction stir welding of nuclear waste canisters

Abstract

The Swedish nuclear waste will be stored in copper canisters and kept isolated deep under ground for more than 100,000 years. To ensure reliable sealing of the canisters, friction stir welding is used. To repetitively produce high quality welds, it is vital to use automatic control of the process. This paper introduces a nonlinear model predictive… (More)
