Abstract EN
This paper studies the robust adaptive fuzzy control design problem for a class of uncertain multiple-input and multiple-output (MIMO) nonlinear systems in the presence of actuator amplitude and rate saturation.
In the control scheme, fuzzy logic systems are used to approximate unknown nonlinear systems.
To compensate the effect of input saturations, an auxiliary system is constructed and the actuator saturations then can be augmented into the controller.
The modified tracking error is introduced and used in fuzzy parameter update laws.
Furthermore, in order to deal with fuzzy approximation errors for unknown nonlinear systems and external disturbances, a robust compensation control is designed.
It is proved that the closed-loop system obtains H∞ tracking performance through Lyapunov analysis.
Steady and transient modified tracking errors are analyzed and the bound of modified tracking errors can be adjusted by tuning certain design parameters.
The proposed control scheme is applicable to uncertain nonlinear systems not only with actuator amplitude saturation, but also with actuator amplitude and rate saturation.
Detailed simulation results of a rigid body satellite attitude control system in the presence of parametric uncertainties, external disturbances, and control input constraints have been presented to illustrate the effectiveness of the proposed control scheme.
