In open-loop control:
Group of answer choices
Results in very small deviations from the optimum variable of the process variable
The open-loop system does not self correct when the process variable drifts
The system is totally immune to external disturbances
The input signal to the controller depends on the actual value of the output variable
Homework Answers
open-loop control is basically designed when there is no external disturbance occurring or its effect is negligible. the plant is always in the same state and there is no much fluctuation in the output, which leads to a stable output without much variation.
as there is nothing to correct any error in the output if it occurs, the open-loop system does not self-correct when the process variable drifts. so remaining options are only applicable to closed-loop systems.

I have some question about PID applied Cruise Control within
Simulink.
First of all, am a bit confused about the the property of PID
applied feedback system. According to the following figure, the use
of a PID controller is to minimize or eliminate the difference
between SP and PV. However, since a transfer function has been
applied to the loop which is the process block in the following
diagram then how the difference could be possibly
erased?

Problem 1 Open-loop tersus Closed-loop control: Consider a first-order system Σ' with inputs (d,u) and output y, governed by Z(t) y(t) ar(t1+hd(t)+5a1(t), cr(t) = = (a) Assume Σ is table (ie, a < 0). For Σ, what is the steady-state gain fron u to y (assuming d 0)? What is the steady-state gain from d to y (assuming t. 0)? These are the open-loop steady-state gains. Call these SSGy and SSGgby respectively (b) Σ is controlled by a "proportional" controller...

True or False/Short Answer Questions The ramp response of a 1st order system can be oscillating. Using the state space representation, the number of rows in the matrix B is equal to the number of outputs. Closed-Loop Control systems are insensitive to external disturbances. Two physically different systems must be modeled by two different transfer functions. For an LTI system, the time derivative of the unit impulse response is the unit ramp response. If a system has two real and...
