Abstract
System stabilization of cos φ is an adaptive system of automatic search in area of the resonance of power circuit, which is form by including a compensating capacitance C in parallel with the electrical drives (inductive - active load) of centrifuges. The resonance corresponds to the extremum - minimum of total current I as a function of the capacitance C. The aim of working an adaptive system is ensured of automatic search dI/dC < 0 in a small neighborhood of the extremum I (C), which provides of the inductive nature of electric power. The operation of the system in a neighborhood of a given dI/dC < 0 is improved by modifying the switching conditions search impact separately for positive/negative steps. The operation of the adaptive control system was represent by simulation results in terms of Simulink (MATLAB). In the process of automatic stabilization Cos φ ∼1 is excluded state of “overcompensation”, the search period is reduced 2-fold relative to the classic of search procedures.
