5-1 Given the open-loop transfer function
s 2 ( s + a ) for a
unity feedback system, please sketch the root locus for
K r = 0 + with different a = 5, a = 9, = 10 .
Please determine the breakaway

Assignment for Chapter 6:
Frequency Domain Analysis
6-1 Using the straight-line approximations, plot the Bode Diagram (Log-magnitude
diagram and Log-phase diagram) of the systems described by the following open-loop
transfer functions. Determine the Gain

Problem 4.1 The system block diagram is as fallows, determine the stability of the system using
Routh criterion, and determine how many roots of the closed loop are in the right half of the

CONTROL ACTIONS
An automatic controller compares the actual value of the system output with the
reference input (desired value), determines the deviation, and produces a control signal
that will reduce

s ( s 1)(2 s 3)
(b) G ( s ) =
K
( s + 2)( s + 4)(s 2 + 6s + 25)
