One of the disadvantage of negative feedback loop is lag caused because it can only be exerted after controlled variable has been disturbed. In order to minimize lag between a change in a controlled variable and the action of the effector, it is advantageous for the body to anticipate any likely change. Which one of the following physiological mechanism achieves this?
Select one:
a. Feedbackward control
b. Feedforward control
c.Positive feedback control
d. All of the above
e. None of the above
Define linear impulse.
(PID solution with the requirements and simple explanation. Thx)
INSTRUCTION: Given three bare processes develop a control system using feedbackand feedforward concept/principle. Your output is a process and instrumentationdiagram (P & ID) using ISA's Instrument Identification and Symbols standards withexplanation.
PROCESS 2: The liquid level inside the tank is regulated at a value of 3.0 m on a condition ofcontinuous liquid inflow and outflow.
Requirements: Two feedback solutions One feedforward solution
