Complexity and onset of chaos control in a DC glow discharge magnetized plasma using all pass filter

Abstract Complexity dynamics of the plasma oscillations is explored under the variation of the discharge voltages in two constant magnetic fields and control of complexity, particularly chaos, has been achieved by using an all pass filter circuit. Appearance of the long diagonal lines in the recurrence plot of the controlled signal, strongly conjecture the regularity of the system after switch on the control. The negative to positive transition of the skewness and the significant change of the intensity of color in the wavelet spectrum also indicates the chaos to order transitions in the plasma system once the control is switch on.
