Algebraic analysis of the structural properties of parametric linear time‐invariant systems

open access: yesIET Control Theory and Applications, 2020
By using techniques borrowed from algebraic geometry, some tests are proposed to certify structural properties (such as reachability, observability, controllability, constructibility, stabilisability, and detectability) of discrete-time and continuous ...

Alphabets of Acyclic Invariant Structures [PDF]

open access: possibleFundamenta Informaticae, 2017
A step trace is an equivalence class of step sequences, where the equivalence is determined by dependencies between pairs of actions expressed as potential simultaneity and sequentialisability. Step traces can be represented by invariant structures with two relations: mutual exclusion and (possibly cyclic) weak causality.

Invariant structure in locomotion

Neuroscience, 1988
Biological systems are hypothesized to control behavior with reference to invariants, because this would allow the variable but robust accomplishment of tasks observed in biological behaviors. Invariants for legged locomotion are specified. Combined with observed properties of locomotion, they lead to predictions of forms of control for legged ...

Structure of index invariant systems

1971 IEEE Conference on Decision and Control, 1971
This paper introduces the concept of a controllability module and then uses it to study certain algebraic properties of index-invariant, time-varying, linear systems. It is shown that controllability modules possess a property similar to the pole placement property of controllability subspaces.
