Abstract :
This paper discusses the design of a state observer for an electric drive with pulse-width modulation of control signal and time division of reconstruction and control processes. An equation was formulated as the basis for the operation algorithm of the switching device, which provides switching on the control action of the electric drive when the transient processes in the state observer are over. The efficiency of the state observer operation algorithm was estimated for the direct current electric drive with a speed regulator.
