At the moment, we are mainly active in (but not restricted to) the following research areas. A list of current projects can be found here.

1. Encoderless control of electrical drives

Speed variable drives require information about the actual position and/or speed of the drive. To provide this information –  without a specific speed or position encoder – saves cost and furthermore increases the reliability of electrical drives. It is necessary to lower the inhibition level to carry the additional investment cost for speed variable (electrical) drives. Our institute has a decisive share in promoting encoderless control to be one of the most investigated technologies for electrical drives recently and globally.

2. Modern control strategies for electrical drives

So-called „intelligent“ control algorithms (predictive, flatness based and non-identifier based adaptive control) provide more  options  to realize a favoured drive behaviour. Amongst others it is possible to consider characteristics like reduced emissions of all kinds, and minimized energy consumption in addition to the basic performance of an electrical drive. Our institute has pushed predictive control to the attention of global research – today there are several institutes in the world investigating in predictive (drive) control.

3. „Hardware-in-the-Loop“ systems

„Hardware-in-the-Loop“ systems  are a highlight in power electronics allowing to model and simulate technical systems on a more sophisticated level. In difference to simulation software running on computers only „Hardware-in-the-Loop“ systems  use real energy guaranteeing the natural behaviour and characteristics of physical energy. In these systems energy is used, but not consumed – the energy is available for further use after the simulation process. In this area our institute is not leading in the world, but contributing significantly to global knowledge.

4. Renewable energy systems (focus on photovoltaics, wind energy & efficiency)

Renewable energy systems (like wind turbine generators and photovoltaic modules) will be in the long term economical and ecological important power sources for power generation world wide. With its expertise in power electronics and electrical drive systems our Institute can significantly contribute in designing and controlling fault-tolerant and energy-efficient renewable energy systems connected to the grid.
