Project Abstract:

The project deals with design of an active seat suspension mechatronic system for autonomous vehicles, including a model predictive control strategy. The final aim is to improve the ride comfort and task execution performance during autonomous driving, where the tasks include reading, writing/typing, and drawing. The project is organized around two research themes. The first theme concerns research and development of two complementary variants of the active seat suspension mechatronic hardware/unit, including a corresponding low-level control system aimed at precise control of vertical force, as well as an techno-economic analysis towards application of the designed mechatronic unit in autonomous and other vehicles. Mathematical and simulation models of the mechatronic unit will be derived for the purpose of low-level control system design, and they will be experimentally verified together with the control strategy. The second theme relates to the design of high-level model predictive control system for active seat suspension, which will employ road profile preview and chassis suspension state feedback. Both linear and nonlinear model predictive control system designs, given in centralized and more practical, decoupled active seat/chassis suspension control variants, will be considered. The designed high-level control strategies will be experimentally verified on a shaker rig, into which the developed active seat suspension mechatronic unit will be integrated. Finally, the test rig-based ride comfort and task execution evaluation will be performed for a large group of examinees, in order to experimentally assess the designed mechatronic system and provide recommendations for its application in autonomous vehicles. The project brings together a multidisciplinary research group, which includes researchers from the areas of mechanical engineering, electrical engineering, and computing, and has a multi-year joint experience in execution of similar projects.
