Design and implementation of water level control for two coupled tank as a simple and low cost apparatus in automatic control engineering education

An autonomous underwater vehicle (AUV) with the advantages of compact structure, good mobility and low-cost will be better used in the field of marine scientific research and military application. This paper introduces the bottom-level control subsystem and autonomous navigation algorithm of the low-cost AUV. In order to prove that the control system has good robustness, some simulations and lake tests were conducted. The results show inertial navigation algorithm based on AHRS, digital compass and GPS can achieve good performance.

The aim of the article is to present the structure of the engineering educational system in Denmark with special emphasis on control engineering education at university level. In comparison with other European countries, the Danish system is unique in including four types of engineering schools: Technical University, Ålborg University Center, Engineering Academy, and Engineering Colleges. The curricula are based on the module systems, which in principle gives students great freedom in selection and combination of courses. For each engineering school the specific requirements and options are listed for lines/branches, which offer specialisation in automatic control. In conclusion the Danish engineering system is briefly compared with the systems in the other Scandinavian countries.

Different Response

This article presents the design of a fuzzy controller embedded in a microcontroller aimed at implementing a low-cost, modular process control system. The fuzzy system's construction is based on a classical proportional and derivative controller, where inputs of error and its derivate depend on the difference between the desired setpoint and the actual level; the goal is to control the water level of coupled tanks. The process is oriented to control based on the knowledge that facilitates the adjustment of the output variable without complex mathematical modeling. In different response tests of the fuzzy controller, a maximum over-impulse greater than 8% or a steady-state error greater than 2.1% was not evidenced when varying the setpoint.
