Chaotic behavior in PWM-based electrical drive with cascade closed-loop control is analyzed. It has been shown that such a system exhibit chaos for wide range of parameters variations. By means of numerical computation several types of system behavior are studied, and corresponding bifurcation diagrams were derived. The diagrams that reflect system behavior dependence on two bifurcation parameters, has been calculated as well. The corresponding phase orbits and time-domain plots are presented. These results may be found as interesting to the scientists and engineers who deal with high-accuracy electromechanical systems and electrical drives.
