This paper presents a control scheme for the speed controller in a 2-mass motor drive system. The speed controller is based on state feedback compensation. The state observer obtains unmeasured states for this system. It is not only accuracte but also fast by utilizing the integrated fuzzy observer. The optimal controller configuration is composed by a load compensator and a linear quadratic (LQ) regulator including an integrator. The load disturbance is directly compensated by the estimated load. Simulation results show that the proposed integrated fuzzy observer provide the better estimation performance than that of the Kalman filter and the proposed control scheme can effectively track the desired speed in the presence of load disturbance
