Abstract
Vacuum plasma spraying (vps) is an industrial technique used to coat substrates in a wide range of materials for numerous applications. Historically, vacuum plasma spraying processes have been open-loop processes with, at most, closed-loop control of the spray parameters. Such processes would benefit from closed-loop control as the issues of process repeatability and coating quality could be addressed. This paper describes the modelling of a vps process and presents a closed loop control strategy based on the model results.
