摘要
High technological process quality requires the use of deviation closed-loop systems and the formation of appropriate informational support for a control process. The article discusses two approaches to obtaining information on displacement components: direct measurement of speed and/or position with the help of a sensor on the motor shaft and indirect determination of the object state vector using the available variables for the direct measurement without the shaft sensor (current and voltage). The main disadvantages of optical encoders are identified. An overview, a classification, a comparative analysis, and the ranges of application of indirect methods of determining displacement components are given (calculation for a model of an electric machine with the measurement of current and voltage of the stator and calculation of the static functional dependence). © 2015, Allerton Press, Inc.
