This paper applies three classical and very popular discrete-time model-based sliding mode controllers, namely the Furuta controller, Gao quasi-relay controller due to Milosavljević, position control of tower crane systems. Three single input-single output (SISO) systems are considered, for cart control, arm angular payload separate SISO controllers designed in each system. Experimental results...

This paper deals with the problem of diagnosing systems that exhibit both continuous and discrete event dynamics. The proposed approach combines techniques from both continuous and discrete event diagnosis fields. On the on hand, an extension of the parity space approach is used to associate signatures to every operational mode of the system. On the other hand, signature switches arising from t...

We investigate how geometry influences spin dynamics in polygonal magnetic nanotubes. find that lowering the rotational symmetry of nanotubes by decreasing number planar facets, splits an increasing spin-wave modes, which are doubly degenerate cylindrical tubes. This symmetry-governed splitting is distinct form topological one recently observed Doublet modes with half-integer or integer multipl...
