1. A controller for directing control of a process, having multiple process parameters (MPPs), performed to control an amount of a pollutant emitted into the air, comprising:

  • one of a neural network process model and a non-neural network process model, the one model representing a relationship between one of the MPPs and other of the MPPs;

    a control processor configured with the logic to determine validity of a measured value of the one MPP based on the one model, and to direct control of the process in accordance with the measured value of the one MPP, only if the measured value of the one MPP is determined to be valid.
