Observer-Based Nonsingular Terminal Sliding Mode Controller Design
This is the paper style requirement for the Chinese Control and Decision Conference. In this paper, a new observer-based nonsingular terminal sliding mode controller is proposed for a spin missile system with inertia uncertainty and external disturbance. By designing the nonlinear disturbance observer to observe the uncertainties and disturbance of the missile system, the chattering of nonsingular terminal sliding mode control is reduced. This controller can make the states not only reach the manifold in finite time, but also obtain a faster convergence and a better tracking precision. The global stability of the closed loop system is guaranteed and the singularity problem associated with conventional terminal sliding mode is avoided. The simulations verified the effectiveness of the proposed method in the paper.
