Question

Transportation lag is seen in systems:

(a) Amount to be transferred in large

(b) Time take to transfer is large

(c) Inefficiency of the process

(d) Errors

This question was posed to me during an interview.

This key question is from Stability Analysis by Describing Functions in section Nonlinear Systems of Control Systems

Answer 1

Right option is (b) Time take to transfer is large

Explanation: Transportation lag is the delay that is seen in the systems where the output is not following the input and is seen in systems where the time taken to transfer is very large.
