Abstract
Abstract The production of start pulses a periodic motion process involves simultaneous generation of a basic train of pulses of a periodic motion phase, at the moment the phase is reached, and a main time interval. The duration of the main time interval is selected in dependence upon the process speed variation pattern. An initial train of pulses of the periodic motion phase, forming part of the basic pulse train, is stored during the main time interval. Upon expiration of the main time interval, an additional time interval is generated equal to at least a fraction of the pulse period of the basic pulse train, with due consideration for the parameters of physical processes influencing the periodic motion. Electric pulses are stored during the additional time interval. Then, at the moment the next phase is reached, a start pulse train is generated and the pulses of the start and initial trains are simultaneously added. As soon as the resultant sum becomes equal to a preset value, the electric pulses stored during the additional time interval are counted down to zero. A start pulse is then generated. The number of pulses in the initial train is k times greater than the number of the basic train pulses occurring during the main time interval. The value k is determined by the ratio of the number of pulses in the start pulse train to the number of pulses in the basic train.
