SYNTHESIS OF THE OUTPUT VOLTAGE REGULATOR OF THE ACTIVE FOUR-QUADRANT RECTIFIER
نویسندگان
چکیده
The analysis of known control systems the active four-quadrant rectifier with pulsewidth modulation applied on a rolling stock electric railway transport, and methods definitionof modal symmetric optimum is carried out. necessity automatic regulation system forstabilization output voltage under condition current change established. controlsystem three-phase basis pulse-width isdeveloped. static characteristic as functionof value load factor determined. It shown that nonlinear, transmission coefficient rectifierdepends current. amplitude-frequency channel theoutput determined, which obtained by adding additional frequenciesto signal measuring these frequencies in form voltage. dynamiccontrol transfer function are simulation ofan frequency 10 kHz theMatlab / Simulink software environment was performed. synthesis regulatorof an performed, ismade optimum. oscillograms transient process outputvoltage during autoregulation obtained. Given fact thecontrol depends current, to obtain uniqueness thetransient when regulating voltage, it necessary create adaptive regulatorfor rectifier.
