Control modeling and regulation of plasma spraying process
- Michigan Technological Univ., Houghton, MI (United States)
Feedback control of plasma spraying will enhance the quality and consistency of coatings by increasing, as in any other process, the immunity of the process against uncertainties, such as parametric variations, and external disturbances. To synthesize any model-based controller for feedback control of the plasma spraying, the control model of the process is needed. In the first part of this study, the input/output data needed for system identification of the process, was generated using a one-dimensional model for the transient fluid flow and heat transfer in the plasma spraying process. In this paper, the data is generated from the solution of the thin-layer-Navier-Stokes (TLNS) equations. As before, the plasma velocity and temperature at the nozzle exit are randomly perturbed about their respective preset operating points. A multi-input-multi-output (MIMO) model is then developed to represent the relationship between the perturbed nozzle exit plasma velocity and temperature and the particle velocity and temperature before impact on the substrate.
