Abstract

Chaos in a fixed frequency dc chopper fed PMDC drive system is realized. The dynamical system is described by the state space representation and differential equations in the continuous conduction mode. Two different tools are used to detect the chaos. The chaotic phenomena is observed by varying the load torque of the motor and speed error amplifier gain. It shows different chaotic behavior when different switching elements are used. The study is helpful in selecting the range and combination of parameters to run the motor at desired speed without chaos.
