Global Controllability of Nonlinear Systems
SIAM Journal on Control, 1972This article deals with the controllability of nonlinear differential systems which arise when a linear system is perturbed. The sufficiency conditions presented insure that the nonlinear system will be (globally) controllable whenever its linear part is controllable. Moreover, the steering can be accomplished using continuous controls with arbitrarily

Feedback control of nonlinear systems
International Journal of Robust and Nonlinear Control, 1992AbstractThis paper deals with the design of (memoryless) state‐feedback laws for systems modelled by nonlinear differential equations which are affine in the inputs. The purpose of the design is to obtain a (locally) internally stable closed‐loop system in which the effect of exogenous inputs on a prescribed error (or, more in general, on a penalty ...

Reliable control of nonlinear systems
IEEE Transactions on Automatic Control, 2000Summary: In this paper, we extend Veillette's results [\textit{R. J. Veillette}, Automatica 31, No. 1, 137-143 (1995; Zbl 0825.93249)] to the study of a reliable linear-quadratic regulator problem for nonlinear systems. This is achieved by employing the Hamilton-Jacobi inequality in the nonlinear case instead of algebraic Riccati equation in the linear

Controllability of nonlinear control systems
1986 25th IEEE Conference on Decision and Control, 1986Controllability properties of analytic affine control systems ? with an arbitrary number of controls and no a priori bounds are studied, without any restriction on the dimension of the Lie algebra T' generated by the input vector fields. Sufficient conditions for local controllability at a point are presented, involving the Lie brackets at that point ...

Controllability of nonlinear stochastic control systems
Systems & Control Letters, 1982Abstract In the paper sufficient conditions for ‘deterministic weak controllability’ of nonlinear Ito equations of the form d x(t)= f(x(t))+ ∑ t=1 m u t (t)g t (x(t)) d t+ ∑ j=1 l h j (x(t)) dw j . 1⩾0,x(0)=P{}∈R n are given.

Controllability of nonlinear systems
IFAC Proceedings Volumes, 2003Abstract In the paper, infinite-dimensional, continuous-time control systems described by certain nonlinear abstract differential equations are considered. Using methods of functional analysis sufficient conditions for constrained exact local controllability are formulated and proved.

A note on the controllability of nonlinear systems
Mathematical Systems Theory, 1984A question of the controllability of nonlinear systems is considered. On the basis of theorems due to \textit{L. M. Graves} [Duke Math. J. 17, 111- 114 (1950; Zbl 0037.204)] a new sufficient condition for local controllability is established.

On the robust control of nonlinear systems
Circuits, Systems, and Signal Processing, 1994In this paper we consider robust stabilization of the class of nonlinear plants of the form $$\dot x = f(x) + \sum\limits_{i = 1}^m {g_i } (x)u_i (t),$$ which are equivalent, under smooth state space coordinate transformations and nonlinear state feedback, to controllable systems.

Control of Uncertain Nonlinear Systems
Journal of Dynamic Systems, Measurement, and Control, 1993This paper describes some of my research in the analysis and control of nonlinear uncertain systems in which the uncertainties are modeled deterministically rather than stochastically. The main applications are to mechanical/aerospace systems, such as robots and spacecraft; the underlying theoretical approach is based on Lyapunov theory.
