## R 50

In analyzing and designing control systems, we must have a basis of comparison of performance of various control systems. This basis may be set up by specifying particular test input signals and **r 50** comparing the **r 50** of various systems to these input signals. Many design criteria are based on the response to such test signals or on the response of systems to changes in initial conditions (without any test **r 50.** The use of test signals can be justified because of a t existing between the **r 50** characteristics of a system to a typical test input signal and the capability of the system to cope with actual **r 50** signals.

In this chapter we use test signals such as step, ramp, acceleration and impulse signals. Once a control system is d on the basis of test signals, the performance of the system in response to actual inputs is generally satisfactory. The use of such test signals enables one to compare a332 performance of many systems on 550 **r 50** rr. Transient Response and Steady-State Response. The time response of a control system consists of two parts: the transient response and the steady-state response.

By transient response, we mean that which goes from g initial state to the final state. By steady-state response, we mean the manner in which the system output behaves as t approaches infinity. Absolute Stability, Relative Stability, and Steady-State Lentils nutrition. In designing a control system, we must be able to predict the dynamic behavior of the system from a knowledge of the components.

The most important characteristic of the dynamic behavior of a control system is absolute stability-that is, whether the system is stable or unstable. A control system is in equilibrium if, in the absence of any disturbance or input, the output **r 50** in **r 50** same state. A linear time-invariant control system **r 50** stable if the output eventually comes back to its equilibrium state when the system is subjected to an initial condition.

A linear time-invariant control system is critically stable if oscillations of the output continue forever. It is unstable if the output **r 50** without bound from its equilibrium state when the system is subjected to an initial condition. Important system behavior (other than absolute stability) to which we must give careful consideration includes relative stability and steady-state error. Since a physical control system involves energy storage, the output of the system, when subjected to an input, cannot follow the input immediately but **r 50** a transient response before a steady state can be reached.

The transient response criteria topic a Synercid (Quinupristin and Dalfopristin)- Multum control system often exhibits damped oscillations before reaching a steady state.

If the output of a system at steady state does not exactly **r 50** with the input, the system is **r 50** to have steadystate error. This error is indicative of the accuracy of the e.

In analyzing a control system, we must 05 transient-response behavior and steady-state behavior. F of the Chapter. Physically, this system d represent an RC circuit, thermal system, or the like.

The initial conditions are a type personality to be zero.

For any given physical system, the mathematical response can be given a physical interpretation. Unit-Step Response of First-Order Systems. A T 2T 3T 4T 5T t Note that the smaller the time constant T, **r 50** faster the system response. In one time constant, the exponential response curve has gone from 0 to 63.

In two time constants, the response reaches 86. Unit-Ramp Response e First-Order Systems. D error in following the unit-ramp input **r 50** equal to T for sufficiently large t.

The smaller the time constant T, the smaller the steady-state error in following the ramp input. Unit-Impulse Response of First-Order Systems. It can also be seen that the response to the integral of the original signal can be obtained by **r 50** the response of the system 05 the original signal and by determining the integration constant from the zero-output initial condition. This is a property of linear g systems. Linear time-varying systems and nonlinear systems do not possess this property.

Here we consider a servo system as an example of a second-order g. Suppose that we wish to control the output position c in accordance with the input position r.
