This project focuses on the control of high speed permanent magnet synchronous machines (PMSM). These electric motors have a high power density and are frequently used in embedded applications such as cars or aircrafts.
Supported by GREEN, ActiMic project is based on the complementarity of two research teams:
- The “high-speed motor control” theme for various industrial applications is a research field carried by GREEN,
- The “on-board microgrid” theme used in avionics, trains and electric vehicles is already well developed and studied at LEMTA.
It consists, on the one hand, in introducing a control without position sensor using a new state observer. The second part of the project, in which LEMTA is involved, aims at guaranteeing, via a specific control, that the system connected to the microgrid does not cause instabilities. The LEMTA teams will study the dynamic behavior of the system when it is connected to a DC microgrid. The objective is to reach a stability of the system whatever the load variations. The theoretical results obtained will be validated experimentally by the LEMTA teams on the microgrid platform. In this objective, the project plans to develop an actuator to validate the performances and study the quality of the control laws developed. The project will last 7 months and will start in June and end in December 2021. A post-doc is currently being recruited for a period of 7 months.
