Some extensions of variable structure control theory for the control of nonlinear systems
1990The main goal of this chapter is to describe new tools in the analysis of discontinuous control systems and to show, with some significant control problems, how the VSC approach yields efficient and robust control, compared with other techniques used to deal with the same problems.

Decomposition and control of a class of nonlinear stochastic systems: theory and its application
Proceedings of the 2001 American Control Conference. (Cat. No.01CH37148), 2001In 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.

Nonlinear Systems in Optimal Control Theory and Related Topics
1983This paper describes the formal dynamic programming derivation of certain nonlinear PDE relevant in control theory and explains some recent work regarding the solution of these problems. These PDE are either first order (deterministic control) or second order, elliptic (stochastic control), and are either a system (if it costs to switch the control) or

Design of Satellite Control System Using Optimal Nonlinear Theory
Mechanics Based Design of Structures and Machines, 2006Nowadays, attitude control systems (ACS) of satellites demand better performance, resulting in the application of new advanced nonlinear control theory. In this paper, a nonlinear control law for a satellite attitude control is presented. It is based on an extension of the linear quadratic regulator (LQR) theory.

On the Centralized Nonlinear Control of HVDC Systems Using Lyapunov Theory
IEEE Transactions on Power Delivery, 2013The security region of a power system is an important and timely issue; different stability criteria may be limiting. Rotor-angle stability can be improved by modulating active power of installed high-voltage direct current (HVDC) links. This paper proposes a new centralized nonlinear control strategy for coordinating several point-to-point and ...
