摘要
In this work, a method for controlling chaotic systems by means of pulses, with four variants, is presented, and its real time application to a particular electronic chaotic circuit (Kiers-Schmidt-Sprott, KSS) is analyzed. Periodic behavior (periodic orbit, PO) is obtained from chaotic dynamics, with a control law depending on a variable event condition, which is automatically adjusted for each particular chaotic process. No previous knowledge of the mathematical model of the system to control is needed, which is considered as a black-box process. Sample data of only one measurement variable and three tuning parameters (proportional gain, pulse width, and hold-off time) are used. Satisfactory real time experimentation results have been obtained using dSPACE 1104 target for the KSS circuit.
