Control of Wind Energy Turbines (CWET)

Control plays a key role in conception, design and operation of wind turbines. The controller adapts the turbine to particular external conditions and operation conditions (e.g. yaw control, torque-speed control, pitch control, etc.). A well-balanced controller can improve the performance of a wind turbine significantly and can help to reduce mechanical loads. On the contrary, a bad controller may eliminate the performance of turbine components. Simply speaking, there is no "good" wind turbine without a "good" controller. The course Control of Wind Energy Turbines (CWET) teaches the foundations of the modelling, analysis and control synthesis of linear systems with a focus on wind turbines.

The module gives 6 CP and is offered in summer semesters.


PD Dr.-Ing. habil. Adrian Hector Gambier, External Lecturer, Fraunhofer IWES Bremerhaven

Adrian Gambier has long-term experience in different areas of control technology. Since 2011, he is senior scientist at the Fraunhofer Institute for Wind Energy Systems in Bremerhaven and is responsible for the development and implementation of control concepts in the context of turbine simulation. 

Learning Objectives

The module CWET gives insights into manifold competences in the area of wind turbine control. After successful completion, the students can

  • develop a simplified dynamic model of a wind turbine,
  • describe the components of a wind turbine mathematically,
  • analyse the system properties of a wind turbine on the basis of a dynamic model,
  • understand the control tasks in the context of wind turbine design,
  • design a PID pitch controller, and
  • prepare a control algorithm for digital implementation.


 The lecture of the module CWET contains the following content:

  • Introduction to control technology
  • Modelling of dynamic systems: Derivation of linear differential equations, transfer function, state space description, dynamic modelling of a wind turbine
  • Analysis of dynamic systems: Analysis in the time and frequency domain, root locus plots, stability analysis, controllability and observability
  • Control design: Control tasks in the context of wind turbines, PID control and parameter adjustment, cascade control, individual pitch control, real time implementation


In parallel to the lectures, students practise the learned know-how in accompanied tutorials. Some of the tutorials take place in the CIP pool with a PC, in which simulations strengthen the understanding of control technologies for wind turbines.


For successfully completing the module, students have to pass an oral exam. The oral exam has a duration of approximately 20 minutes.

Students have to enroll for the exam online at the Academic Examination Office (Akademisches Prüfungsamt) within the respective time limits.
