Controlled electric drives can achieve highly precise movement patterns with defined speed/torque profiles, featuring remarkable dynamics and resource efficiency. Whenever there is a need for precise positioning, rapid acceleration and deceleration, or adherence to a defined speed profile, these characteristics are particularly valuable.

Examples include industrial manufacturing processes, goods logistics, transportation, and mobility.

Controlled drives are thus the backbone of many key processes in our modern technological world. They enable the targeted conversion of electrical energy into motion and are a crucial building block of applied automation technology. Without controlled electric drives, industrial manufacturing processes as we know them, goods logistics, transportation, and mobility would be inconceivable.

The module on Controlled Electric Drives explores the architecture and interplay of the key components in controlled electric drive systems, providing a solid introduction to the major control methods used in electric drive technology. It also presents methods for designing and technologically structuring controlled electric drives, as well as discussing the fundamental principles for dimensioning the main components.

The module requires basic knowledge of electrical machines and the most important basic power electronic circuits in drive technology.

Familiarity with control models in MATLAB/Simulink is required.

Upon completing the module,

• students understand the principles and tools for analyzing a motion task with the aim of assembling a suitable drive system, and
• are familiar with the fundamental architecture and specific operational behavior of closed-loop controlled electric drive systems.
• They can identify the key components of closed-loop controlled electric drives and understand how they interact within a system.
• They have been introduced to special configurations of electric machines for use in controlled drive systems
• Particularly permanent magnet-excited machine types.
• Additionally, they can explain the basic principles of the most important control methods for electric drives.

In addition, upon completing the module, students are equipped to:

• analyze a motion task in terms of the parameters essential for selecting an appropriate drive system, both conceptually and through calculations,
• select the most suitable components for closed-loop controlled electric drives and justify their choices,
• understand the operational characteristics of complete drive systems
• and use this knowledge to choose suitable controlled drives, and determine and integrate into a complete system, besides the primary component (the electric machine), other required elements for controlled electric drives to fulfill a defined motion task.

Students who have completed the module on Controlled Electric Drives can analyze specific, defined motion tasks and compare different concepts for controlled drive systems to assess their suitability for the task, thereby concluding which concepts are best suited for the given task.

Additionally, they have learned to apply well-known methods of general control engineering to drive applications and to evaluate which specific challenges need to be addressed in drive technology. Suitable solution strategies have been implemented and verified.

Upon completing the module, students can combine known and newly acquired technical concepts from the fields of electrical machines, power electronics, and control engineering to create a solution for a specific drive engineering problem by designing an appropriate drive system and its control scheme.

Upon completing the module, students are able to identify potential in existing controlled drive systems to formulate research questions and recognize research areas in various subfields of electrical engineering and materials science that can contribute to the development of sustainable controlled drive concepts.

Upon completing the module, students can present their self-developed solutions to drive engineering problems, illustrate the benefits of these solutions, and defend them with sound arguments.
