Digital motor control system

摘要: A control system for one or more dc motors in which thyristor power modules selectively gate portions of half cycles ac voltage to the motor field and armature windings, has digitally implemented parallel inner loops each generate an intermediate signal proportional plus derivative action been applied. Logic selects phases back firing pulses most application a common digital integrator produces having integral action. The across thyristors is monitored used detect continuous discontinuous current operation adjusting gain.
