Abstract:

In this paper, the problem of nonlinear systems robust tracing containing uncertain diathesis, which abstracted from Computer Integrated Manufacturing Systems (CIMS) in wood industry was discussed. Where, unknown parameters taken value from a compact set Ω are time-varying. Furthermore, self-tuning controller of a robust tracking problem is given when unknown parameters appear both linear and nonlinear style.

Key words: Lyapunov function, Robust tracking, Nonlinear uncertain system, Controller
