Mechatronics - Actuation & power electronics

Course overview

Life without motion is unimaginable. This statement is also valid in the production industry.

Electro-mechanic actuators, driven by highly efficient and accurate power electronic circuits, are the working horses within the industry. They determine the performance and quality of many industrial processes. In high-end industrial applications the accuracy of the production systems is increasing steadily, enabled by ever more powerful, precise, efficient and cost-effective actuation systems.

Several questions can be asked about dynamic mechanical systems that are related with the actuation;

These and many other questions will be elaborated in the course. For that reason the fundamentals of electromagnetic actuators and motors including the necessary power electronics to control them will be covered. Detailed attention is given to the challenging task of choosing the right actuator type for a certain application from an overwhelming diversity. The impact of different principles of electronic power conversion will be unraveled, ranging from linear to switched mode power circuits, each with their own benefits and drawbacks. The need for current or voltage drive is elaborated while attention is given for power amplifier noise. Especially aspects of element selection and/or development for short stroke or long stroke high precision linear actuation will be treated and special multi-DOF actuators will be presented as challenging examples.
