<p>This paper describes a novel fuzzy tracking control for permanent magnet synchronous motors (PMSM) using an extended Kalman filter (EKF) and disturbance observer (DO). The goal is to create robust controller able drive the system’s states track virtual reference model provide low effect on machine. First, PMSM represented Takagi-Sugeno (T-S) attended by load torque variation. Next, To ...

The application scope of unmanned aerial vehicles (UAVs) is increasing along with commensurate advancements in performance. hybrid quadrotor vertical takeoff and landing (VTOL) UAV has the benefits both rotary-wing aircraft fixed-wing aircraft. However, vehicle requires a robust controller for takeoff, landing, transition, hovering modes because aerodynamic parameters differ those modes. We con...

A Smith-Dynamic Matrix Control ( DMC ) -PID SDP control method based on disturbance observer is devised for the temperature regulation of a reactor with high lag and nonlinear features. This results in poor system stability low precision. In first place, because prone to receiving external disturbances generated by changes, which ultimately leads significant impact inside kettle, introducing PI...

Abstract: In this paper, a time varying disturbance observer subject to sampled data’s measurements is proposed for a class of non-linear systems. The proposed observer combines the advantage of a high gain structure in terms of convergence speed and an output predictor which remains continuous between the sampling times. The exponential convergence of the proposed observer is proved using a Ly...
