The disadvantages of the error constants are:
A. They do not give the information of the steady state error when the inputs are other than the three basic types
B. Error constant fail to indicate the exact manner in which the error function change with time.
C. They do not give information of the steady state error and fail to indicate the exact manner in which the error function change with time
D. They give information of the steady state error
Answer:C
The disadvantages of the error constants are:
A. They do not give the information of the steady state error when the inputs are other than the three basic types B. Error constant fail to indicate the exact manner in which the error function change with time. C. They do not give information of the steady state error and fail to indicate the exact manner in which the error function change with time D. They give information of the steady state error
Explanation: The disadvantages of the error constants are as they do not give the information of the steady state error when the inputs are other than the three basic types and error constant fail to indicate the exact manner in which the error function change with time.
