Steve Miller, MathWorks

Engineers designing yaw and pitch actuators for wind turbines need to take into account many of the other components in the overall system to produce an optimized design. Selecting a technology requires doing tradeoff studies in early stages to determine which will provide enough force or torque while drawing the least power. The actuator must be developed together with the control systems, and there may be multiple control systems that must interact with the actuation system. For the development process to be efficient, engineers must have the ability to determine which details will be included in the simulation and which will be neglected. The models that they produce must be realistic and reusable.

The model of a complete wind turbine (including mechanical, electrical and hydraulic systems) will be used to show:

• How to use simulation to determine detailed, up-to-date requirements based on the overall system design
• How to develop electrical and hydraulic actuation systems based on those requirements
• How to define custom, reusable components using the Simscape language
• How to use optimization algorithms and measurement data to automatically determine realistic parameter values

These points will be illustrated with demonstrations using the model and the simulation software. Experience with MATLAB and Simulink is helpful, but not required to learn from this webinar.

Model-Based Design of a Wind Turbine  27:12
Developing wind turbines requires a smooth, continuous development process in which modeling and simulation plays a large role. From the earliest design phase to the automatic generation of production code, engineers need the ability to test new idea

Determining Mechanical Loads for Wind Turbines  34:03
Determining the mechanical loads a wind turbine experiences is a complex process that requires more than just a model of the mechanical system. To accurately predict maximum loads, deflections, and oscillations, the entire system must be modeled in o

Designing Control Systems For Wind Turbines  34:22
The number and complexity of control systems in wind turbines is expanding rapidly, and their design can be the difference between an immensely profitable system and a dormant or damaged system. Designing a robust control system requires an accurate
