Design of robust controller by neuro-fuzzy system in a prescribed region via state feedback

In this paper, first a new algorithm for pole assignment of closed-loop multi-variable controllable systems in a prescribed region of the z-plane is presented. Then, robust state feedback controllers are designed by implementing a neural fuzzy system for the placement of closed-loop poles of a controllable system in a prescribed region in the left-hand side of z-plane. A new method based on the...

Nonlinear state feedback for ( 1 optimal control

This paper considers 61 optimal control problems with full state feedback. In contrast to ,~ optimal control, previous work has shown that linear {1 optimal controllers can be dynamic and of arbitrarily high order. However, this paper shows that continuous memoryless nonlinear state feedback performs as well as dynamic linear state feedback. The derivation , which is nonconstructive, relies on ...

Global Robust State-Feedback for Nonlinear Systems via Dynamic High-Gain Scaling

We propose state-feedback controller design methodologies using our recent results on uniform solvability of state-dependent matrix Lyapunov equations. The controller designs obtained do not involve recursive computations and have a simple form being essentially a linear feedback with state-dependent dynamic gains. Furthermore, the Lyapunov functions utilized in the designs are quadratic functi...

Recent Advances in Nonlinear Optimal Feedback Control Design

This paper presents a detailed perspective of two constructive feedback strategies characterized by algebraic Riccati equations for solving continuous-time nonlinear deterministic optimal control problems. In each case, the system is first transformed into a linear-like, state-dependent structure. The first method is based on treating the adapted model as an instantaneously linear time-invarian...
