Singular perturbation theory in control of nonlinear systems with uncertainties

2016 24th Iranian Conference on Electrical Engineering (ICEE), 2016
In this paper, a control approach is proposed for stabilization of nonlinear systems in the presence of both matched and unmatched uncertainties. By combining the time scale separation and backstepping, first, high-gain filters are designed to estimate the uncertainties, and then, a fast dynamical equation is derived which the solution is found to ...

Theory of cone methods for null controllability of nonlinear control systems

IEEE Transactions on Automatic Control, 1979
Cone-valued Lyapunov functions have been used by several authors to examine the stability of nonlinear systems. However, the general problem of constructing a suitable cone given the nature of nonlinearity seems to be as difficult as that of constructing a suitable Lyapunov function.

Decomposition and control of a class of nonlinear stochastic systems: theory and its application

Proceedings of the 2001 American Control Conference. (Cat. No.01CH37148), 2001
In this paper, we design control algorithms and derive sufficient criteria for the stability and robustness of nonlinear stochastic systems. The Lyapunov stability theory is used. The results documented are verified by studying examples. In particular, a high-performance servo-system with an electric motor is examined.
