This article proposes a feasible method for a class of nonaffine‐in‐control nonlinear systems in the presence of input saturation to obtain performance recovery. In the previous work, the plant is required to be affine‐in‐control to derive the difference between the desired and saturated inputs. Considering the nonaffine structure, we first build a fast subsystem with respect to the nominal system, where no saturation is presented. Then, an intermediate subsystem is established to compensate the influence of input saturation by approximating the difference between the original and nominal systems. In the slow time‐scale, a series of existing control methods can be combined to achieve the requested transient performance. The ability of performance recovery is proved rigorously by the singular perturbation theory. Numerical examples are illustrated to demonstrate the validity of the presented method.

“…From the studies reported in [21,22], it is possible to conclude that HG-ESOs presents better performance for EHA systems under parametric uncertainties and model nonlinearities. The HG-ESO in [21,22] is analyzed using simulated and experimental tests compared with conventional observers, demonstrating estimation of full state variables and total disturbances. Furthermore, time-varying observers with an exponential convergence were presented in [24][25][26][27][28][29].…”

With the development of on-orbit missions, solid propulsion technology is applied to the rapid orbital maneuver of satellites. During solid propulsion maneuver, the position change of the mass center caused by the fuel consumption and the installation error of thruster have brought serious attitude disturbances. For this problem, a novel prescribed time attitude control method is proposed in this paper. Firstly, a dynamics model of the solid propulsion micro-satellite is established, while the thrust direction is adjusted by the thrust vector control (TVC) nozzle. Then, a constraint boundary function is constructed to characterize the strict fixation of the thruster operating time and an adaptive fuzzy observer is developed to quickly estimate the lumped model uncertainties. Using the backstepping method, a novel prescribed time attitude control strategy regardless of initial conditions is designed. Simulation results show that the designed controller can achieve the prescribed time convergence of satellite attitude during solid propulsion orbital maneuver, effectively.
