Input constraints as well parametric uncertainties must be accounted for in the design of safe control systems. This paper presents an adaptive controller multiple-input-multiple-output (MIMO) plants with input magnitude and rate saturation presence uncertainties. A filter is introduced path to accommodate limits. An output feedback designed stabilize closed loop system even this filter. The ov...

For the challenging problem that a spacecraft approaches tumbling target with non-cooperative maneuver, an anti-saturated proximity control method is proposed in this paper. First, brand-new appointed-time convergent performance function developed via exploring Bézier curve to quantitatively characterize transient and steady-state behaviors of pose tracking error system. The major advantage act...

the quality of the river water is assessed in different months in different stations to evaluate the change in the quality in re1ation with the various point sources along the river. thirteen parameters were measured in the samples manually taken from three meters off shore in 20 cm. depth in four points representing the quality in four reaches under consideration. the results revealed that nat...

In this work, a controller is developed for continuous bioreactor with an unknown reaction rate term, subject to input saturation. The substrate concentration and the dilution are chosen as output input, respectively. formulation stability analysis performed by theory of dead zone Lyapunov functions, stability, model reference adaptive control. As main results, dynamics function determined sepa...
