Abstract

Anti-control and synchronization of period doubling and chaos is a method for bifurcation control. It can be used to detect the occurrence or periodic behavior of a bifurcation at the specified position to meet the requirements of brushless direct current (BLDCM). Antichaotic control can be implemented through the use of an external periodic term or constant. The study of the parametric singularities of brushless direct current (BLDCM) allows the identification of a complex bifurcation structure, namely the limit point (LP), the Hopf (H) and the Bogdanov-Takens (BT) bifurcations, the period-doubling bifurcation and path to chaos . By adjusting the control parameters of the controller, the period doubling bifurcation can be generated or suppressed at the specified position to realize the anti-control of period doubling and chaos bifurcation. Parametric singularities are analyzed using a variety of anti-control signals, including constant voltage, periodic square, sawtooth wave, triangle, etc. The simulation results show that adding constant or periodic factors improves chaos and anti-control effects.

摘要

倍周期分岔与混沌的反控制是一种分岔控制方法。它可用于检测指定位置分岔的发生或周期性行为，以满足无刷直流电机（BLDCM）的要求。反混沌控制可通过使用外部周期项或常数来实现。对无刷直流电机（BLDCM）的参数奇点进行研究，可识别出复杂的分岔结构，即极限点（LP）、霍普夫（H）和博格达诺夫 - 塔克恩斯（BT）分岔、倍周期分岔以及通向混沌的路径。通过调整控制器的控制参数，可在指定位置产生或抑制倍周期分岔，以实现倍周期和混沌分岔的反控制。使用多种反控制信号（包括恒定电压、周期性方波、锯齿波、三角波等）对参数奇点进行分析。仿真结果表明，添加常数或周期因素可改善混沌和反控制效果。
