Abstract
A servomotor velocity control system has an estimating unit (4) for obtaining an estimated value (V) of velocity based on rotary encoder position information (.theta.), which includes a current (I.sub.L) indicative of load torque, and motor current (I) of a servomotor (5). The system is adapted to obtain a torque command signal (U) based on the estimated value (V) of velocity and a velocity comman signal (V.sub.c).
