Short Desciption:
In order to do systematic analysis and control design, it is necessary to have a model of the process. A tool for assessment of process dynamics and nonlinearities has been developed. It is based on transient response analysis of the process. The emphasis has been on creating a user interface for graphical manipulation of step responses in a natural way.

Summary:
Modeling. In order to do systematic analysis and control design, it is necessary to have a model of the process. A tool for assessment of process dynamics and nonlinearities has been developed. It is based on transient response analysis of the process. The emphasis has been on creating a user interface for graphical manipulation of step responses in a natural way.
Improved controller tuning. Existing autotuning methods for PI and PID controllers typically use a simple process model with a few parameters. More advanced design methods require more detailed models, which may be difficult to identify automatically. This thesis presents a method to generate a suitable excitation signal under relay feedback, and an identification scheme which gives a process model that can be used for advanced design of PI and PID controllers. It is shown that the PI design method can be applied iteratively in order to obtain good PID controllers.
Fast grade changes. The PI and PID controllers are mainly suited for regulation problems. When large set point changes are desired, process operators often use manual control until the process output is close to the desired value. This thesis presents an automated procedure which mimics the manual control actions done by the process operator. The method may be applied with limited process knowledge.
