PCT No. PCT/JP85/00620 Sec. 371 Date Jul. 2, 1986 Sec. 102(e) Date Jul. 2, 1986 PCT Filed Nov. 7, 1985 PCT Pub. No. WO86/03074 PCT Pub. Date May 22, 1986.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 (IL) 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 (Vc).
