Abstract

An adaptive control for a process is disclosed which utilizes a process parameter calculator made up of simple function blocks which generate a plurality of process parameters, and a tuning parameter calculator, also made up of simple function blocks, for calculating tuning parameters from the process parameters. The process parameter calculator is provided with values for various disturbances, a set point, a control output from a process controller and process structure data including process sensitivity and nominal operating data. From these values, the process parameters are determined. The tuning parameter calculator is provided in addition to the process parameters, with performance parameters and design function for generating tuning parameters that are applied to the controller for modifying the control output in response thereto.
