Robust Chaos occurring in piecewise smooth dynamical systems is very important in practical applications. It is defined by the absence of periodic windows and coexisting attractors in some neighbourhood of the parameter space. In earlier works, the occurrence of robust chaos was reported in the context of piecewise linear 1D and 2D maps, and regions of occurrences have been investigated in 1D and 2D switching circuits. Here, it has been reported the first experimental observation of this phenomenon in a 3D electronic switching system and obtain the region of parameter space by constructing a discrete map of the system.
