DIGITAL SERVOSYSTEM Russian patent published in 1995 - IPC

FIELD: servosystems in automatics. SUBSTANCE: digital servosystem uses as an actuating organ a direct current motor, whose deceleration is being provided due to self-induction emf without overrunning and transient processes in the system. The system has the unit 5 for determining a rotation sign and an angular error, comparing codes of a remote computer and of a feedback circuit of the digital pickup 4. A signal, corresponding to a difference of the control codes, had been fed, is being formed in outputs of the unit 5. A sign of that signal determines a rotation direction of a shaft of an actuating electric motor 3 and also a difference code, setting a time moment of beginning of deceleration mode of the motor. In the result the first decelerating pulse in the system is being formed before coincidence of control codes and of the feedback codes. EFFECT: enhanced quick action of systems. 1 cl, 6 dwg
