Abstract: The invention relates to a method for the automatic generation of a control process program on a computer. One illustrative embodiment, referred to as STAR-GEN, is described as it might be implemented on a general purpose computer using a suitable high-level language such as Fortran. Through a graphical user interface, STAR-GEN prompts the user for (1) system specific information, (2) problem-specific information, and (3) control process-specific information. When all of these data have been entered, STAR-GEN automatically generates a process control (source) program which is independent of a target computer platform. This source program can be transferred to a specific process control computer where it is compiled for execution using a standard, for example Fortran, compiler. A unique and beneficial aspect of the invention includes its ability to provide the user with a consistent development environment regardless of the specific hardware platform (computer) the process control program is to execute on.

Abstract: A method of controlling a process having a plurality of independently controlled, manipulated variables and at least one controlled variable which is dependent on the manipulated variables. In the first step of the method data is gathered about the process by introducing test disturbances in the manipulated variables and measuring the effect of the disturbances on the controlled variable. The value of the controlled variable is measured at a first time. Using the data gathered from the test disturbances and the measured value of the controlled variable, a first set of changes in at least one of the manipulated variables is calculated such that the controlled variable is driven towards its set point without exceeding a predetermined limit. The manipulated variables are adjusted in accordance with at least one change from the first set of calculated changes. The values of the manipulated variables and the controlled variable are then measured at a second time.
