It has been demonstrated previously that some switched mode power electronic circuits such as buck and boost converters, pulse-width-modulated converters etc can exhibit chaos for significantly large ranges of parameter values. Such power electronic devices are often used as power-conversion units in modern electrical drives. Therefore, it is interesting to study the possibility of chaotic behavior in closed-loop electrical drives, and its influence on drive performance. In this paper we present our results in theoretical analysis of bifurcation and chaos in a PWM-based cascade control electrical drive. The paper also presents the well-known phenomena of unpredicted occurrence of high levels of torque pulsations and jitter, explained through bifurcation and chaos. The corresponding phase orbits on the speed-torque plane and bifurcation diagrams are presented. These results can also be useful for electromechanical engineers.
