Controller system for variable parameter and related program product

摘要

A controller system includes at least one computing device operably connected to a process having a target value for a variable parameter. The computing device(s) is configured to control the variable parameter by performing actions including: computing an error between the target value and an actual value of the variable parameter. Based on the error, the computing device(s) may calculate a desired gain adjustment of the variable parameter, and a desired mean adjustment of the variable parameter. A correction signal may be created for modifying the process by: in response to the error being positive, creating the correction signal by adding the desired mean adjustment and the desired gain adjustment, and in response to the error being negative, creating the correction signal by differencing the desired mean adjustment and the desired gain adjustment. A related program product may carry out similar functions.
