“…When uncertainty and disturbance are involved, the dynamics of one-link manipulator can be expressed as the following form: 3 , and g 3 (x 3 ) = 1/M. It is apparent that the numerical example (75) is suitable for the case of system (1).…”

“…If the input saturation is ignored in the control design, the closed-loop control performance will be severely degraded, and instability may occur. In recent years, there have been extensive studies on various systems with input saturation in [1]- [3]. Neural network (NN)-based near-optimal control was developed for a class of discretetime affine nonlinear systems with control constraints in [4].…”

“…Recently, the digital techniques has been developing rapidly, many control methods of discrete-time systems have been used in practical engineering [6,7]. Some researchers discretized continuous systems with timedelays into equivalent discrete form in order to deal with the time-delays by discrete methods [8,9].…”

“…Consequently, it is very necessary to take the input constraints into account during the attitude controller design [15][16][17][18][19][20][21]. For the linear system, predictive control [22] and optimal control [23] have been applied to treat problems with input constraints, whereas the control system must be determined a priori and no disturbances are considered yet. The problem of input constraints for aerospace application is considered in reference [24], in which an anti-windup control scheme was proposed for the large-angle attitude control of a spacecraft under actuator saturation.…”
