Flatness: an overview
A control system is called flat if its solutions can be parameterized by a set of "free" functions and their derivatives. Initially developed for finite-dimension nonlinear systems, flatness can be seen as a notion of equivalence to a trivial system by a so-called endogenous feedback. It provides simple solutions for motion planning as well as for tracking (for instance by dynamic feedback linearization), which are two central problems in control theory. Though this flatness property is very strong, it is interesting in practice as many engineering systems are flat. The idea was later adapted to infinite-dimension control systems, and turned out to be fruitful even in the linear case, for instance for motion planning of partial differential equations with boundary control.

The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land granted to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is co-ordinated within the Office of Indigenous Relations.
