Which type of control provides more stable levels of our regulated variables?Question 15Answera.Proportionalb.On/Offc.Differentiald.Homeostatic

The most stable control of our regulated variables is provided by Homeostatic control.

Here's why:

a. Proportional control: This type of control responds to the deviation from the set point proportionally. However, it cannot eliminate the error completely, leading to a steady-state error.

b. On/Off control: This is the simplest form of control but it leads to oscillations around the set point.

c. Differential control: This type of control responds to the rate of change of error signal. It can lead to instability if not properly tuned.

d. Homeostatic control: This type of control maintains the stability of a system by constantly adjusting its conditions to the set point. It's the type of control our bodies use to maintain a stable internal environment, despite changes in external conditions. For example, our bodies maintain a relatively stable body temperature, blood pH, glucose concentration, etc., through homeostatic control. Therefore, it provides the most stable levels of our regulated variables.
