Abstract

The study introduces an overview of chaos in nonlinear systems. Chaos is governed by deterministic laws but is so unpredictable because its sensitivity depends on initial conditions. Chaotic behaviors in electric drive systems have been explored by scientists. The investigation into chaos in electric drive systems can be categorized as three themes, namely the analysis of chaotic phenomena, the control of chaotic behaviors, and the application of chaotic characteristics. Then the analysis and simulation of a squirrel cage induction motor detects chaos through time plot, phase diagram and Lyapunov exponents. Therefore, the sensitivity to parameter variations of induction motors (resistance; inductance; stator and rotor leakage reactance; mutual inductance) affects the quality of controller and can be the cause of the chaotic system.
