The number G(0) is called the

**static gain**of the system because it tells the ratio of the output and the input under steady state condition. The**transfer function**can thus be viewed as a generalization of the concept of**gain**.What is pole and zero in transfer function?

**Poles and Zeros**of a

**transfer function**are the frequencies for which the value of the denominator and numerator of

**transfer function**becomes

**zero**respectively. The values of the

**poles**and the

**zeros**of a system determine whether the system is stable, and how well the system performs.

## What is the closed loop transfer function?

**Closed**-

**loop transfer function**. From Wikipedia, the free encyclopedia. A

**closed**-

**loop transfer function**in control theory is a mathematical expression (algorithm) describing the net result of the effects of a

**closed**(feedback)

**loop**on the input signal to the circuits enclosed by the

**loop**.

## What is Laplace transfer function?

To find the complete response of a system from its

**transfer function**: Find the zero input response by using the**transfer function**to find the zero input differential equation. Take the**Laplace Transform**of that equation (including initial conditions), and solve.3

## What is Mason's gain formula?

**Mason's gain formula**. From Wikipedia, the free encyclopedia.

**Mason's gain formula**(MGF) is a method for finding the transfer function of a linear signal-flow graph (SFG). The

**formula**was derived by Samuel Jefferson

**Mason**, whom it is also named after.

## What is the use of transfer function in neural network?

An artificial

**neuron**is a mathematical**function**conceived as a model of biological neurons, a**neural network**. Usually each input is separately weighted, and the sum is passed through a non-linear**function**known as an activation**function**or**transfer function**.5

## What is the gain of a control system?

**Gain**is a proportional value that shows the relationship between the magnitude of the input to the magnitude of the output signal at steady state. Many

**systems**contain a method by which the

**gain**can be altered, providing more or less "power" to the

**system**.

## What is the state space?

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 or difference equations. The "**state space**" is the Euclidean**space**in which the variables on the axes are the**state**variables.7

## What is the steady state error of a control system?

**Steady**-

**state error**is defined as the difference between the input (command) and the output of a

**system**in the limit as time goes to infinity (i.e. when the response has reached

**steady state**). The

**steady**-

**state error**will depend on the type of input (step, ramp, etc.) as well as the

**system**type (0, I, or II).

## What are poles and zeros?

**Poles and Zeros**of a transfer function are the frequencies for which the value of the denominator and numerator of transfer function becomes

**zero**respectively. The values of the

**poles**and the

**zeros**of a system determine whether the system is stable, and how well the system performs.

## What is the DC gain of the system?

**DC Gain**. When a stable control system is excited with a step input, the response. attains a constant level at steady state. The term

**DC gain**is defined as the. amplitude ratio between the steady state response and the step input.

10

## What is S in a transfer function?

**Transfer Function**. The

**Transfer function**of a system is the relationship of the system's output to its input, represented in the complex Laplace domain. If the complex Laplace variable is

**s**, then we generally denote the

**transfer function**of a system as either G(

**s**) or H(

**s**).

## What do you mean by transient response?

In electrical engineering and mechanical engineering, a

**transient response**is the**response**of a system to a change from an equilibrium or a steady state. The**transient response**is not necessarily tied to abrupt events but to any event that affects the equilibrium of the system.12

## What is peak overshoot?

In control theory,

**overshoot**refers to an output exceeding its final, steady-state value. For a step input, the percentage**overshoot**(PO) is the maximum value minus the step value divided by the step value. In the case of the unit step, the**overshoot**is just the maximum value of the step response minus one.13

## What do you mean by control system?

A

**control system**manages, commands, directs, or regulates the behavior of other devices or**systems**using**control**loops. It can range from a single home heating controller using a thermostat controlling a domestic boiler to large Industrial**control systems**which are used for controlling processes or machines.14

## What is the use of Bode plot?

In electrical engineering and control theory, a

**Bode plot**/ˈbo?di/ is a graph of the frequency response of a system. It is usually a combination of a**Bode**magnitude**plot**, expressing the magnitude (usually in decibels) of the frequency response, and a**Bode**phase**plot**, expressing the phase shift.15

## What is signal flow graph in control system?

A

**signal**-**flow graph**or**signal**-**flowgraph**(SFG), invented by Claude Shannon, but often called a Mason**graph**after Samuel Jefferson Mason who coined the term, is a specialized**flow graph**, a directed**graph**in which nodes represent**system**variables, and branches (edges, arcs, or arrows) represent functional connections16

## What is the root locus?

In control theory and stability theory,

**root locus**analysis is a graphical method for examining how the**roots**of a system change with variation of a certain system parameter, commonly a gain within a feedback system.17

## What is the impulse response of the system?

In signal processing, the

**impulse response**, or**impulse response**function (IRF), of a dynamic system is its output when presented with a brief input signal, called an**impulse**. More generally, an**impulse response**is the reaction of any dynamic system in**response**to some external change.
