An Equalizing Network for Carrier-Type Feedback Control Systems
C. Looney · Proceedings of the IRE · 1955
Lag type compensation of a speed regulating system may be used to reduce the steady state error. The analysis of an active, high Q, RLC circuit shows that it permits lag compensation of carrier-type feedback control systems through direct operation on the system actuating signal. The use of this circuit in an instrument type velocity servo reduces the steady-state error by a factor of at least 30.
