Test Waveforms Used in Control Systems 20

Impulse n n Infinite at t = 0 and zero elsewhere Used for obtaining the transient response of the system and from this derive the mathematical model of the system 21

Step n n Represents a constant command It is used, because both the transient response and the steady-state response are clearly visible and can be evaluated 22

Ramp n Represents linearly increasing command 23

Parabola n Similar to the previous case 24

Sinusoid n Used to test a physical system to arrive at a mathematical model 25

Example 26

Answer A n A = V 0 (t)/Θi (t) = DV/10 =100/10 = 10 V/turn 27
