Abstract
In this article, the problem of synthesizing correction devices with the given quality indicators is set and solved. The systems of the phase-locked loop (PLL) of the second and third order, as most commonly found in practice, are investigated. The algorithm of synthesis of PLL system correction device by the root trajectory method is considered. The possibility of a significant reduction of the velocity component of the PLL system error in the presence of correction is shown. The variants of implementation of the adjusting device using the operational amplifier are given. It is shown that the introduction of a sequential correction device in a closed control circuit can improve the accuracy in the steady state and improve the quality of the transient process of the system. The possibilities of synthesis and evaluation of quality indicators of PLL systems are considered, as well as the construction of transition curves and frequency characteristics without the use of auxiliary charts, nomograms and tables. There is presented the method of synthesizing the coremigal extension of the systems of phase auto tuningis assigned for assigning viewers an anchor for the method of trajectory roots. It is shown, for a particular system of phase auto tuning, that is introduced after the control device in the closed loop, the control is enabled to adjust the accuracy in the idle mode and the polarity of the overflow system. Showing the possibility of the a substantial reduction of the speed error warehousing system of phase auto tuning for correction.Globally, the possible synthesis of the feedback of phase auto tuning scoring systems.
