摘要

For a class of nonlinear systems, which are subject to unknown dead-zone and control directions, this chapter considers their tracking control problem. By using adaptive control technology, with the help of fuzzy logic systems, an adaptive fuzzy control strategy is given. From Lyapunov stability theory, it is proven that tracking errors converge to the neighborhoods of the origin. Simulation results show the effectiveness of the strategy proposed in this chapter.
