Digital control systems for asynchronous electrical drives with vector control principle

Abstract

Problems of optimizing the operation modes of an asynchronous electric drive according to the criterion of the minimum stator current, as well as the optimal control system of an asynchronous motor with a reference rotor flow vector, which can be used for most serial frequency converters, longitudinal components of the stator current are added to the control channel.

Microprocessor Analog I/O Modules

“…In modern systems, various topologies, levels and methods of interrogating the measuring data module are used. The data input/output modules used are equipped with built-in microprocessors that programmatically poll channels in accordance with the algorithm for the operation of the servicing system for all active channels [1].…”

Development of a digital signal processing model using a frequency synthesizer and synthesis of quadrature conversion circuits

“…The above expressions do not take into account quantization noise, and the selected frequency band must be wide enough to analyze real signals. Further, comparing the natural decomposition coefficients previously obtained by formulas (3) and ( 5), we obtain the actual real deviation parameters [13,16,17],…”

Algorithmic Methods for Increasing the Metrological Characteristics of Information-Measuring Systems

“…and the known amplitude-frequency characteristic or IR of such a digital filter, it is possible to identify the permissible level of error dispersion for input signals2 , which has a direct dependence on the bit depth b of the numbers that are samples of the input signals[10].…”
