Former of Turn Trajectory of Sliding Valve Shaft of Gas Line

Former of turn trajectory of sliding valve shaft of gas line, that allows to provide desired motion trajectory of sliding valve and its full closing, is considered in that paper. Imitation model of that former, research results, which allow to detect influence of gain factor and time constant of position controller on value of speed error, that has impact on delay of output coordinate from setting, and that results to delay of sliding valve motion process to setting position point, are shown

Functional Control Synthesis of Single-Phase Low Power Motor Drives

In the paper an electric drive system of series-wound universal motor powered by semiconductor converter is considered.The system characteristics and calculation procedure using spectral method of Solodovnikov and aligning procedure areshown. We derived and displayed expressions for two-dimensional non-stationary transfer functions and non-stationaryspectral characteristics of output variables of automated control system of single-phase series-wound universal motorpowered by semiconductor converter. We also show results of electromagnetic calculation of the electric drive system ofseries-wound universal motor powered by semiconductor converter for various firing angles ? of the converter, as welldependences of conduction angle ?t for varied values of rotational speed ? and load torque on the shaft of the moto
