Answer:
The attached system shows that there’s an integrator between the point where disturbance enters the system and error measuring element. A any time when R(s)=0 then
and considering that
then
For ramp disturbance d(t)=at
therefore, the steady state error is given by
Whenever
has a double intergrator, the error
becomes zero
Answer:
The right answer is "2.2099 m³".
Explanation:
Given:
Mass,
m = 5 kg
Temperature,
T = 35℃
or,
= 35 + 273
Pressure,
P = 200 kPa
Gas constant,
R = 0.2870 kj/kgK
By using the ideal gas equation,
The volume will be:
⇒ 
or,
⇒ 
By substituting the values, we get
