A multilayer controller (610) that is used to direct the operation of a system (620) for a process. The process has many parameters (MPPs) (625), MPPs (625) at least one of controllable process parameters (CTPP) (615) and MPPs (625) one of the target parameters (TPP) (625). The process also has a defined target value (DTV), said on AAV2 TPL in length: limited time period TPP (625) of the actual value (AAV) of the first limit. Calculates the AAV based on the actual value of the TPP (AVs) within the specified period. The first logic controller (630) in the first prediction of future time period (FFTP) in TPP (625) (FAVs), the future value of the first period of future time length of at least TPL: AAV2 and T from the current time: 0 extends to the future time: AAV2 T, in the before, TPP (625) will move to a steady state. Based on (I) in the first period of time first (FPTP) each time the TPP (625) AAVs, the first time the first cycle length of at least TPL: AAV2 and T: from the first time AAV2 extended to the current time: T 0 (II (MPPs). The current value of 625), and DTV (III), to predict FAVs. Second future time period to determine the second logic controller (SFTP) to the target value (FTV), said on TPP (625) AAV second, SFTP TPL length: AAV1, which is smaller than the length of TPL: AAV2 and T, from the current time: 0 extends to the future time: T AAV1. The FAVs is determined based on one or more of the predicted TPP's in the FFTP FTV. The second is based on logic controller (I), second in the earlier time period (SFTP) each time the TPP (625) AAVs, the first time the second cycle length of TPL: AAV1 and T: \from the first time AAV1 was extended to the current time: T 0, (II MPPs) (625) the current value, and (III) FTV, to determine each CTPP (615) of the target set point. The second logic controller also has logic to direct the control of each CTPP (615) in accordance with the determined target set point of CTPP (615).
