2010年10月13日 · Controllability. Definition: An LTI system is controllable if, for every x (t) and every finite T > 0, there exists an input function u(t), 0 < t ≤ T , such that the system state goes from x(0) = 0 to x(T ) = x .
1.7 Controllability Gramian Problem: Given x(0) = 0 and any x¯, compute u(t) such that x(t¯) = ¯x for some ¯t > 0. Solution: We know that x¯ = x(t¯) = Z¯t 0 eA(t¯−τ)Bu(τ)dτ. If we limit our search to controls u of the form u(t) = BTeAT(¯t−t)z¯ we have x¯ = Z¯t 0 eA(¯t−τ)BBTeAT(¯t−τ)zdτ,¯ = Z ¯t 0 eA(¯t−τ)BBTeAT ...
linear systems: stability, controllability, and observability. In brief, a linear system is stable if its state does remains bounded with time, is controllable if the input can be designed to take the system from any
Controllability and Observability in Control System
2024年2月27日 · Controllability is the ability to control the state of the system by applying specific input whereas observability is the ability to measure or observe the system’s state. In this article, we will study controllability and observability in detail.
Controllability of complex networks - Nature
2011年5月11日 · Here we develop analytical tools to study the controllability of an arbitrary complex directed network, identifying the set of driver nodes with time-dependent control that can guide the system...
Controllability and state transfer • state transfer • reachable set, controllability matrix • minimum norm inputs • infinite-horizon minimum norm transfer 18–1
Controllability plays an essential role in the development of modern mathematical control theory. There are various important relationships between controllability, stability and stabilizability of linear both finite-dimensional and infinite-dimensional control systems. Controllability is also strongly related with the the-
Controllability - an overview | ScienceDirect Topics
Controllability involves dynamic states and is the capability of achieving a goal within a prescribed timeframe, whereas flexibility deals with steady-state conditions. The controllability concept regarding resilience can be defined as designing processes that are almost under control.
