This article addresses the problem of balancing an inverted spherical pendulum on a quadrotor. The full dynamic model is obtained via Euler-Lagrange formalism, where dynamics coupled to quadrotor, taking as control inputs torques associated with yaw, roll, and pitch dynamics, input for vertical displacement in height. A trajectory tracking scheme proposed by means active disturbance rejection b...

Stroke is a worldwide disease with high incidence rate. After surviving stroke, most patients are left impaired upper or lower limb. Muscle force training vital for stroke to recover limb function and improve their quality of life. This paper proposes tracking control method based on functional electrical stimulation (FES), which promising rehabilitation approach. A modified Hammerstein model p...

A new tracking design for laser systems with different arrangements of a quadrant photodetector, based on the principle of active disturbance rejection control is suggested. The detailed models of quadrant photodetector with standard add–subtract, difference-over-sum and diagonal-differenceover-sum algorithms for displacement signals are included in the control loop. Target moving, nonlinearity...

The application of new energy systems for industrial production to advance air pollution prevention and control has become an irreversible trend. This development includes hybrid consisting reversible solid oxide cells (RSOC) a Li-ion battery; however, at present the dispatching such unstable factor in form poor heat/electricity/gas controllability. Therefore, system studied this paper uses bat...
