Could you teach me the way to solve Lab 1,2?
Ans 1:
in MATLAB command prompt
G = tf([1],[1 1])
G = tf([2],[1 2])
G = tf([3],[1 3])
G = tf([4],[1 4])
to find settling time in MATLAB use below function
stepinfo(G)
for a = 1
settling time: 3.9121s
rise time:2.1970s
for a = 2
settling time: 1.9560s
rise time:1.0985s
for a = 3
settling time: 0.7323s
rise time:1.3040s
for a = 4
settling time: 0.5493s
rise time:0.9780s
to plot poles and zero use below command in MATLAB
pzmap(G)
pole zero plot for a = 1
for a =2
for a=3
for a = 4
Ans 2:
in MATLAB command prompt
G= tf([25],[1 4 25])
