Waste-water treatment test plant control. Computer aided modern control teaching

Abstract:

An experimental work on the control design for waste-water treatment test-plant control computer aided modern control teaching has been conceived. The work presents three sucesive stages: First, the student must identify the process with the instrumentation available at the control laboratory. He shall use a personal computer with A/D and D/A converters connected to the process as well as a software package suitable for identification. In a second step, the student must analyze the process as well as design a digital regulator to get the desired behaviour of the global process according to the requirements previously established by the teacher. In the last step, each student or group of them must verify their design in the test plant and must explain the conclusions about the practical results they have obtained. Our work has been prepared on the test plant in such a way that different control schemes can be implemented.
