This paper dealed with position control problems of a DC motor servo system that had nonlinear friction and was subject to parametric uncertainties  external disturbances  etc. In order to overcame those unfavourable factors mentioned above  a model reference adaptive control method was proposed to regulate the important and main speed loop in the positioning system which was designed with three closed control loop  where a compensatory measure was given so as to counterbalance the friction torque disturbances. In addition  the other two close loops were built in adjusting the position and the current of the servo system respectively that aimed to achieve the fast and precise positioning and increase dynamic stiffness against load disturbances. Experimental results illustrate satisfactory performances in steady state error  load capability  high rapidity and so on. 2010 IEEE.
