Horseshoes, homoclinic connections and global chaos in current-mode controlled DC/DC converters
— In this paper, chaos in a current-mode controlled boost converter is studied. Firstly, the existence of chaos is proven theoretically in this system. The proof consists of show...

Reducing Delay Jitter of Real-Time Control Tasks through Adaptive Deadline Adjustments
For many control systems, control performance is strongly dependent on delay variations of the control tasks. Such variations can come from a number of sources including task preem...

Asymptotic approach on conjugate points for minimal time bang-bang controls
We focus on the minimal time control problem for single-input control-affine systems x = X(x) + u1Y1(x) in IRn with fixed initial and final time conditions x(0) = ^x0, x(tf ) = ^x...
