Abstract: A method for adjusting at least two parameters of a coating process to manufacture a coated transparent substrate including a multi-layered coating according to a targeted value for at least one quality function for the coated transparent substrate. The method relies on a set of different mathematical prediction models in the training procedure, which, once trained, when they are used either sequentially, alternatively or in parallel, during the prediction procedure, allow to counteract or counterbalance drifts that may potentially occur from one of them. Outstanding benefits are that misbehaviours of current feedback methods may be prevented, that changes in the local atmosphere of deposit cells, and in turn in the chemistry of coated layers, which may occur from temperature and/or humidity variation, may be compensated, and that more than one coating process parameters may be adjusted at the same time.
