Technical development in industry requires a harmony between the controlled process, the control system and the human. This requirement needs to use safety and fast bi-directional communication. The tool for this goal is the efficient and accurate real-time control. Some technologies consist of extremely fast and extremely slow processes. Extremely fast processes require high-powered data collection and data conversion, high-speed process control system with extremely short real-time cycle, high computational capability, and high memory capacitance. Extremely slow processes require continuous communication with the process to perceive slow and fine changes, ability to distinguish a finite state of process from any temporary state of process, and capability to recognize and evaluate the relatively faster short- time events. The goal of this work is to develop a new method to achieve higher efficiency and safety in controlling of large-scale systems by Thom''s catastrophe theory. The new method will be introduced by a large-scale system, the steam production technology which includes extremely fast and extremely slow processes.
