直流传动系统中不稳定周期轨道的镇定

Stabilization of unstable periodic orbits in dc drives

Krishnendu Chakrabarty, Urmila Kar

摘要:

以直流并励电动机或永磁体直流电动机为原动机的电力拖动系统存在分岔和混沌现象。直流并联和永磁直流电动机的特性本质上是线性的。这些电动机是由脉冲宽度调制(PWM)技术与半导体开关的帮助下控制。这些开关是在驱动器中引入非线性特性的非线性元件。任何非线性系统都可能存在分岔和混沌。直流并联或PMDC驱动器在一定的参数值范围内显示正常行为。还观察到,这些驱动器显示出显着大范围的参数值的混乱。在本文中,我们提出了一种方法控制适用于直流并联和PMDC驱动器的混沌。数值研究的结果。

英文摘要:

Electric drive using dc shunt motor or permanent magnet dc (PMDC) motor as prime mover exhibits bifurcation and chaos. The characteristics of dc shunt and PMDC motors are linear in nature. These motors are controlled by pulse width modulation (PWM) technique with the help of semiconductor switches. These switches are nonlinear element that introduces nonlinear characteristics in the drive. Any nonlinear system can exhibit bifurcation and chaos. dc shunt or PMDC drives show normal behavior with certain range of parameter values. It is also observed that these drive show chaos for significantly large ranges of parameter values. In this paper we present a method for controlling chaos applicable to dc shunt and PMDC drives. The results of numerical investigation are presented.
