This paper shows the behavior of a Three-phase power converter with resistive load using a quasi-sliding control technique for output voltage regulation and a novel control technique to control chaos. The controller is designed using Zero Average Dynamic (ZAD) and Fixed Point Inducting Control (FPIC) techniques. The designs have been tested in a Rapid Control Prototyping (RCP) system based on Digital Signal Processing (DSP) for dSPACE platform. The results show that the phase voltage in the load has sinusoidal performance when it is controlled with these techniques. Bifurcation diagrams varying a control parameter show the robustness of the system. Experimental and simulations results agree only when delay effects are considered in simulations. After this consideration, numerical and experimental bifurcations diagrams agree both in stable zone as well as in transition to chaos. Chaos detection is a kind of signal processing method within the scope of time domain, and has power quality phenomena detection applications.
