Recently, Adaptive critic design (ACD) has been applied to controller design extensively. It is a powerful approach to cope with the model nonlinearity and uncertainties. Existing ACD-based controllers have been proven as uniformly ultimately bounded (UUB). However, UUB only makes the tracking error converge to a certain bounded region. Although we can minimize the bounded region by increasing the...
A new guidance law for multipurpose unmanned attack air vehicle (MUAAV) is proposed. It is the improved proportional navigation guidance law by employing the continuous time nonlinear predictive control theory, i.e. the predictive proportional navigation guidance law. As same as many other guidance law, this guidance needs information about the target acceleration for its implementation, but the target...
A new adaptive fuzzy control algorithm which combines sliding mode controller and a proportional-integral controller into a single adaptive fuzzy sliding mode controller (AFSMC) is proposed for a nonlinear system - an inverted pendulum system. The AFSMC can tackle the control problem of unknown nonlinear systems and systems with modeling uncertainties and external disturbance. The role of the controller...
