After deriving a mathematical model of a system, the system performance analysis can be done in various methods.
In analyzing and designing control systems, a basis of comparison of performance of various control systems should be made. This basis may be set up by specifying particular test input signals and by comparing the responses of various systems to these signals.
The system stability, system accuracy and complete evaluation are always based on the time response analysis and the corresponding results.
Next important step after a mathematical model of a system is obtained.
To analyze the system's performance.
Normally use the standard input signals to identify the characteristics of system’s response
· Step function
· Ramp function
· Impulse function
· Parabolic function
· Sinusoidal function
