Control of MR actuators for the automotive industry

Since 2013, Exonetik has been developing and manufacturing magnetorheological (MR) actuator systems that enable novel functionalities to satisfy unmet customer needs. Exonetik’s patented actuator systems offer a unique combination of force-density, high bandwidth, superior back-drivability, low cost and aerospace-level reliability. Since 2016, Exonetik has been working with major companies in the automotive industry such as Magna International. One field of application of the automotive industry where MR actuators are bringing value is active suspensions.
Since 2016, Magna Corporate has partnered with Exonetik to develop multiple prototypes of active seat suspension which were used for market validation and technical feasibility investigation. Exonetik has proven with these prototypes that MR actuators have exceeded the expected performance and cost targets and that the technology is mature enough to be commercialised within a two-year timeframe. In June 2019, Magna Seating (subdivision of Magna International) officially launched a development program to bring the active seat suspension to production in July 2021.
The purpose of this MITACS research project is to collaborate with Exonetik team’s in the development of a production ready active suspension system for class 8 trucks. The Mitacs intern will be responsible for the refinement of the control algorithms of the active seat suspension system.
