On Output Feedback Invariants and Cascade Equivalence of Systems
نویسنده
چکیده
The paper is concerned with the algebraic classii-cation problem of linear systems up to static output feedback. Using tools from geometric invariant theory it is shown that there exists a quasi pro-jective variety whose points parameterize the output feedback orbits in a unique way. If the McMil-lan degree n mp then the set of output feedback orbits of nondegenerate transfer functions of size p m is a quasi projective variety.

Singular Perturbation Theory in Output Feedback Control of Pure-Feedback Systems
This paper studies output feedback control of pure-feedback systems with immeasurable states and completely non-affine property. Since availability of all the states is usually impossible in the actual process, we assume that just the system output is measurable and the system states are not available. First, to estimate the immeasurable states a state observer is designed. Relatively fewer res...
متن کاملSignature submanifolds for some equivalence problems
This article concerned on the study of signature submanifolds for curves under Lie group actions SE(2), SA(2) and for surfaces under SE(3). Signature submanifold is a regular submanifold which its coordinate components are differential invariants of an associated manifold under Lie group action, and therefore signature submanifold is a key for solving equivalence problems.

This paper considers the problem of adaptive output feedback tracking control for a class of nonstrict-feedback nonlinear systems with unknown time-varying delays and unknown backlash-like hysteresis. Fuzzy logic systems are used to estimate the unknown nonlinear functions. Based on the Lyapunov–Krasovskii method, the control scheme is constructed by using the backstepping and adaptive techniqu...
