Journal Title: Електромагнітна сумісність та безпека на залізничному транспорті - Year 2018, Vol 1, Issue 16
Abstract
The article is dedicated to the regulation of regulation of the speed of the electric drive. It is noted that the main way of imparting astatic properties to an automatic system is to use integrat-ing corrective devices-regulators. The phenomenon of parametric astatism is established and the conditions for its occurrence are found. The phenomenon of parametric astatism in a complex electromechanical system of speed control for an AC electric drive with an asynchronous motor and vector control is considered. It is shown that parametric astatism takes place in two-mass electric drives of direct and alternating current with a constant and variable as a function of the load speed, provided that the control part of the system is synthesized using root methods. This applies to systems of modal control and systems where the synthesis of low-order rate controllers is based on the polynomial method. It is determined that the majority of the standard distribu-tions considered above allow one to obtain parametric astatism in the system.
