Optimal control problems and variational inequalities form a rich interdisciplinary area that bridges the disciplines of mathematical analysis, numerical methods and engineering applications. At its ...

The Takagi--Sugeno (T--S) fuzzy descriptor system offers a promising avenue for controlling non-linear systems but lacks optimal control strategies. Moreover, while robust control methods have been ...

At each sampling time instant, one observes system output and action to form discrete-time rewards. The sampled input-output data are collected along the trajectory of the dynamical system in ...
