Abstract
A method for controlling an industrial process, such as a paper machine, is devised to handle multiple manipulated and controlled variables of the process. The method includes making available for selection a plurality of different multivariable sub-control systems for controlling the process. A user interface table is generated and displayed showing configuration information about the plurality of multivariable sub-control systems. A selection of one of the multivariable sub-control systems is received through the user interface and used by the computer system for configuring the multivariable control system and performing control calculation for the multivariable control system.
Claims20
A method for creating a control system for an industrial multivariable process with one or more manipulated variables and one or more controlled variables, the method comprising:
- creating a first table, wherein one or more manipulated variables are assigned to one or more sub-control systems and wherein each manipulated variable is assigned to no more than one sub-control system;
- creating a second table, wherein one or more controlled variables are assigned to the one or more sub-control systems;
- using the first and second tables to generate one or more sub-process response models;
- and
- using the one or more sub-process response models to generate the one or more sub-control systems, which are operable to control one or more sub-processes, each sub-control system including a set of tuning parameters.
