State space (controls) — In control engineering, a state space representation is a mathematical model of a physical system as a set of input, output and state variables related by first order differential equations. To abstract from the number of inputs, outputs and… … Wikipedia
State variable — A state variable is an element of the set of variables that describe the state of a dynamical system.In case of simple mechanical systems, position coordinates and their derivates are typical state variables. Temperature, pressure, internal… … Wikipedia
State (patrón de diseño) — El patrón de diseño State se utiliza cuando el comportamiento de un objeto cambia dependiendo del estado del mismo. Por ejemplo: una alarma puede tener diferentes estados, como desactivada, activada, en configuración. Definimos una interfaz… … Wikipedia Español
State observer — In control theory, a state observer is a system that models a real system in order to provide an estimate of its internal state, given measurements of the input and output of the real system. It is typically a computer implemented mathematical… … Wikipedia
State variable filter — A state variable filter is a type of active filter. It consists of one or more integrators, connected in some feedback configuration. Any LTI system can be described as a state space model, with n state variables for an nth order system. A state… … Wikipedia
State vector — *A state vector in general control systems describes the observed states of an object in state space, e.g. in variables of the degrees of freedom for motion (i.e. translatory variables distance, velocity and acceleration for location and… … Wikipedia
