The overall goals of the new teaching concepts are to consolidate the student's control theory knowledge, to establish practical relevance of the lectures, to gain experience and to develop creativity as well as team-working skills. A laboratory is planned as an introduction to automatic control for students with no engineering background. The goal is to give the students a practical and basic overview of control theory. In addition, a student contest is introduced, which is focused on autonomous vehicle control problems such as path following and advanced cruise control.
An Innovative Method for Rotor Inertia Emulation at Wind Turbine Test Benches

For several reasons the rotors of such turbines are dismounted at test benches, through which the dynamic properties of the system are changed significantly. This results in the challenge of having to emulate the missing rotational inertia for realistic wind turbine controller tests. In this paper an innovative method is proposed, which allows the emulation of the missing rotational inertia. The idea of the proposed method is to balance the inertia related torque by controlling the rotational impulse of the wind turbine's drive train. This has the advantage, that compared to a baseline approach, this method does not require a rigid drive train at the test bench to accurately emulate the rotor inertia. For this reason the proposed method reproduces the drive train's dynamics more accurately than the ba...

At the same time large structures, such as the blades and the tower get more flexible. To minimize this impact, the classical control loops for keeping the power production in an optimum state are more and more extended by load alleviation strategies. These additional control loops can be unified by a multiple-input multiple-output (MIMO) controller to achieve better balancing of tuning parameters. An example for MIMO control, which has been paid more attention to recently by wind industry, is Model Predictive Control (MPC). In a MPC framework a simplified model of the WT is used to predict its controlled outputs. Based on a user-defined cost function an online optimization calculates the optimal control sequence. Thereby MPC can intrinsically incorporate constraints e.g. of actuators.

Self-optimising systems with their ability to analyse data, to model processes and to take decisions offer an approach to master processes without explicit control functions. After a brief introduction, two approaches of self-optimising strategies are presented. The first example demonstrates the autonomous generation of technology models for a milling operation. Process knowledge is a key factor in manufacturing and is also an integral part of the self-optimisation approach. In this context, process knowledge in a machine readable format is required in order to provide the self-optimising manufacturing systems a basis for decision making and optimisation strategies. The second example shows a model based self-optimised injection moulding manufacturing system. To compensate process fluctuations and guarantee a constant part quality the manufactured products, the self-optimising approach uses a model, which describes the pvT-behaviour and controls the injection process by a determination of the process optimised trajectory of temperature and pressure in the mould.
Driving Torque Control for a Nacelle Test Bench

Some experience has been gained during the last years with drive train test benches, that allow for pure mechanical and electrical tests of the turbine's components. Since the loads occurring inside a wind turbine significantly depend on its control strategy, the natural extension of drive train test benches are so-called nacelle test benches, which also include the wind turbine's controller. The worldwide first nacelle test bench was installed and launched at RWTH Aachen University in 2013. This nacelle test bench was set up as a demonstrator and has a rated power of 1 MW.
