What are state variables in control system?

A state variable is one of the set of variables that are used to describe the mathematical “state” of a dynamical system. Intuitively, the state of a system describes enough about the system to determine its future behaviour in the absence of any external forces affecting the system.

Which is not a state variable?

State function is a proterty of a system that depends only on its present state, which is completely determined by variables such as temperature and pressure. Thus. Internal energy and volume are state function. On the other hand, heat and work are not state functions becasue they are not properties of a system.

What is state of system in control system?

A state variable is one of the set of variables that are used to describe the mathematical “state”of a dynamical system. Intuitively, the state of a system describes enough about the system to determine its future behaviour in the absence of any external forces affecting the system.

Which of the following variables determine the state of a system?

Variable like P,V and T are called state variable (or state functions) because their values depend only on the state of the system and not on how it is reached.

Which mechanism in control engineering implies an ability to measure the state by taking measurement at output?

Observability
Explanation: Observability and controllability are the two methods to check the output response characteristics and observability in control engineering implies an ability to measure the state by taking measurements at output.

What is the difference between state variable and state function?

While state variables only depend on the initial and final states irrespective of path followed to reach the stage. State function – doesn’t depend on path and only on the initial and final states.

Which one is not state function?

Heat and work are not state functions. Work can’t be a state function because it is proportional to the distance an object is moved, which depends on the path used to go from the initial to the final state.

Which of the following are not state functions?

Heat (q) and work (W) are not state functions being path dependent. A state function is the property of the system whose value depends only on the initial and final state of the system and is independent of the path. It is a state function because it is independent of the path.

Which of the following variables are called state variables or state functions?

T, P and V are state variables or state functions.

Which of the following variables Cannot be state function?

State function is a proterty of a system that depends only on its present state, which is completely determined by variables such as temperature and pressure. On the other hand, heat and work are not state functions becasue they are not properties of a system.

Which of the following is not a state variable Mcq?

The correct option is B) Temperature, pressure, volume are examples of state variables.

Which among the following constitutes the state model of system in addition to state equation?

Which among the following constitute the state model of a system in addition to state equations? Explanation: Output Equations constitute the state model of a system in addition to state equations and for the complete state model mainly input model, output model and state models are required.
