Control of tidal turbine drive systems

Abstract

In this report, the function, model and data of a tidal turbine drive system are summarized. The emphasis is placed on the methods which are used to design a controller to improve the performance of the tidal turbine drive system in the following aspect, the faster response time and less overshoot.

A growing attention to the greenhouse effect caused by converting the energy of fossil fuels has been paid in the whole world, which leads to the utilizing clean and renewable energy source to decrease the using of fossil fuels. There are various kinds of renewable energy, and tidal energy is one of them. Tidal energy is still a new form of renewable relatively, but the methods of harnessing the tidal energy are similar to wind energy. Generally the Horizontal Axis Wave Turbine(HAWT) is chosen to harness the tidal energy due to its better efficiency. To improve the performance of the system, a controller is installed in generally. PID controller is widely used in industrial control systems, because of its effectiveness, robust, insensitive and simple to be setup and maintained.

The objective of this project is to set up a model of tidal turbine drive system, design control scheme to improve the performance of tidal turbine drive system and evaluating the system performance by computer simulation.
