From Pure State and Input Constraints to Mixed Constraints in Nonlinear Systems

Authors: Willem Esterhuizen, Jean Lévine, in Feedback Stabilization of Controlled Dynamical Systems, pp. 125-141, Nicolas Petit Ed., Vol. 473 in Lecture Notes in Control and Information Sciences, Springer-Verlag, March 24 2017. DOI: 10.1007/978-3-319-51298-3_5
We survey the results on the problem of pure/mixed state and input constrained control, with multidimensional constraints, for finite dimensional nonlinear differential systems with focus on the so-called admissible set and its boundary. The admissible set is the set of initial conditions for which there exist a control and an integral curve satisfying the constraints for all time. Its boundary is made of two disjoint parts: the subset of the state constraint boundary on which there are trajectories pointing towards the interior of the admissible set or tangentially to it; and a barrier, namely a semipermeable surface which is constructed via a generalized minimum-like principle with nonsmooth terminal conditions. Comparisons between pure state constraints and mixed ones are presented on a series of simple academic examples.
