Background
Inverters are used in automotive industry to be able to control electrical machines to produce the desired speed and torque to propel the vehicle. For induction machines, both the magnetization level and the torque of the machine are controllable quantities. However, as electrical machines are non-linear devises the selection of the optimal operating currents for a given operation point is not trivial.

Scope

Objectives:

Create/develop scripts to define the maximum torque per ampere for an induction machine for its entire operating range.

Activities:

• Literature study of what previously has been done in this field.
• Make non-linear model of induction machine.
• Make field-oriented controller algorithm for the induction machine.
• Make MTPA script which optimizes the current set-points to use during operation.
• Final report which describes findings and the method of selecting the optimized set points.

Do you fit the profile
We are looking for master students with a preferred background and experience from electrical power engineering and electrical machine control. Aiming for students studying MPEPO at Chalmers. This thesis work requires skills in Matlab & Simulink needed.
