Example :
a) Data
– Motors characteristics:
LM = 5 mH
RM = 5 W
LM / RM = 1msec
– Voltage and current characteristics:
Vs = 20 V
IM = 2 A
VI = 9.1 V
– Closed loop bandwidth : 3 kHz
b) Calculation
From relationship (4) :
and from (1) :
RC = 1 msec [from expression (2) ]
Assuming
ξ = 1/
; from (7) follows :
The cutoff frequency is :
