چکیده
Based on previous work, a Nussbaum gian controller is proposed to solve the unknown input direction problem of a large family of supersonic missiles. Also considering the one order dynamic characteristic of actuator , the uncertainties of nonlinear missile system, which is assumed to satisfy the socalled bounded uncertainty condition, are coped by the adopting of integral action and backstepping technology.And the unknown control direction problem of supersonic missile is solved by adopting of the Nussbaum gain method. A novel analysis with Lyapunov function and Nussbaum gain function are completed and the stability of the whole system is guaranteed by constructing of the Lyapunov function.

The thin-layer Navier-Stokes equations are solved for two complete missile configurations on an IBM 3090-200 vectro-facility supercomputer. The conservation form of the three-dimensional equations, written in generalized coordinates, are finite differenced and solved on a body-fitted curvilinear grid system developed in conjunction with the flowfield solver. The numerical procedure is based on ...

In this paper, a fractional-order robust adaptive intelligent controller (FRAIC) is designed for a class of chaotic fractional order systems with uncertainty, external disturbances and unknown time-varying input time delay. The time delay is considered both constant and time varying. Due to changes in the equilibrium point, adaptive control is used to update the system's momentary information a...

متن کاملAdaptive Fuzzy Dynamic Sliding Mode Control of Nonlinear Systems
Two phenomena can produce chattering: switching of input control signal and the large amplitude of this switching (switching gain). To remove the switching of input control signal, dynamic sliding mode control (DSMC) is used. In DSMC switching is removed due to the integrator which is placed before the plant. However, in DSMC the augmented system (system plus the integrator) is one dimension bi...
