    Notizen: This paper presents an efficient method for the design of controllers for integrating and runaway processes. The method is based on model matching in the frequency domain. The presence of open-loop instability as well as pure time delay in the process models make the design task challenging for these classes of processes.The goal is to achieve low-order, easily implementable cascade controllers in a unity-output-feedback configuration. It is shown that the central problem is in the selection of appropriate reference models. Several key constraints are developed which relate a given process model to a class of reference models for achieving total stability. Typical design examples are presented to clearly illustrate the various mathematical techniques.

    Notizen: An efficient frequency domain methodology for the design of set point regulators for high-order process models involving relatively large pure time delay is presented. The unique advantage of the methodology is that it enables the designer to rapidly visualize the structure of the required controller as soon as the time and frequency domain specifications are stipulated for the closed-loop system. Optimizing the parameters of an appropriate structure improves the robustness of the controller. The method does not require order reduction of the original model, and time delay is handled directly. Also, only output feedback is utilized.
