摘要： A controller (610) for directing operation of an air pollution control system (620) performing a process to control emissions of a pollutant has multiple process parameters (MPPs) (625). One or more of the MPPs (625) is a controlla~e process parameter (CTPP) (615) and one of the MPPs (625) is an amount of the pollutant (AOP) (640) emitted by the system (620). A defined AOP (640) value (AOPV) represents an objective or limit on an actual value (AV) of the emitted (640). The controller (610) includes either a neural network process model or a non-neural network process model representing a relationship between each CTPP (615) and the emitted (640). A control processor (630) has the logic to predict, based on the model, how changes to the current value of each CTPP (615) will affect a future AV of emitted AOP (640), to select one of the changes in one CTPP (615) based on the predicted affect of that change and on the AOPV, and to direct control of the one CTPP (615) in accordance with the selected change for the CTPP (615).

摘要： A multi-tier controller (610) directs operation of a system (620) performing a process. The process has multiple process parameters (MPPs) (625), at least one of the MPPs (625) being a controllable process parameter (CTPP) (615) and one of the MPPs (625) being a targeted process parameter (TPP) (625). The process also has a defined target limit (DTV) representing a first limit on an actual average value (AAV) of the TPP (625) over a defined time period of length TPL AAV2 . The AAV is computed based on actual values (AVs) of the TTP over the defined period. A first logical controller (630) predicts future average values (FAVs) of the TPP (625) over a first future time period (FFTP) having a length of at least TPL AAV2 and extending from a current time T 0 to an future time T AAV2 , prior to which the TPP (625) will move to steady state. The FAVs are predicted based on (i) the AAVs of the TTP (625) at various times over a first prior time period (FPTP) having a length of at least TPL AAV2 and extending from a prior time of T -AAV2 to the current time T 0 , (ii) the current values of the MPPs (625), and (iii) the DTV. A second logical controller esta~ishes a further target limit (FTV) representing a second limit on the AAV of the TTP (625) for a second future time period (SFTP) having a length equal to TPL AAV1 which is less than the length TPL AAV2 , and extending from the current time T 0 to a future time T AAV1 . The FTV is established based on one or more of the predicted FAVs of the TPP (625) over the FFTP. The second logical controller also determines a target set 25 point for each CTPP (615) based on (i) the AAVs of the TPP (625) at various times over a second prior time period (SPTP) having the length TPL AAV1 , and extending from a prior time T -AAV1 to the current time T 0 , (ii) the current values of the MPPs (625), and (iii) the FTV. The second logical controller additionally has logic to direct control of each CTPP (615) in accordance with the determined target set point for that CTPP (615).

摘要： A controller directs operation of an air pollution control (APC) system performing a process to control emissions of a pollutant. The process has multiple process parameters (MPPs), one or more of the MPPs being a controllable process parameters (CTPPs) and one of the MPPs being an amount of the pollutant (AOP) emitted by the system. A user input device identifies an optimization objective.
