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...
