Abstract :
This paper proposes and implements a novel electrically chaotic compactor. A modified time-delay feedback control method is applied to chaoize a DC motor in the compactor. The Poincare map, the bifurcation diagram and the maximum Lyapunov exponent are used to analyze the chaos in the electrically chaotic compactor. Simulation comparison not only proves that the electrically chaotic compactor offers better compacting performance than the constant speed compactor but also verifies that the electrically chaotic compactor offers the advantages of good controllability and high flexibility rather than the mechanically chaotic compactor
