At the Precision Mechatronics Laboratory (PML) of the University of Liège, we develop the methods and technologies that allow large scientific instruments to measure the world with extreme accuracy. Our research sits at the crossroads of precision mechanics, sensing, and advanced control, with a focus on understanding, measuring, and actively mitigating vibrations and disturbances that limit performance. From fundamental modelling and system identification to experimental validation on prototypes and test benches, we design complete solutions that combine mechanical architectures, sensors and actuators, real-time control, and data-driven approaches to achieve stable, repeatable, and ultra-low-noise operation. This expertise is naturally connected to the needs of cutting-edge experimental physics and high-precision engineering, where the smallest motion or fluctuation can define the boundary between a good measurement and a breakthrough. Through close collaboration with academic and industrial partners, PML contributes to the broader ecosystem of high-precision instrumentation by training students and researchers, transferring know-how, and building robust engineering approaches that translate ambitious scientific requirements into reliable, deployable systems.
