For a type 0 system, the steady-state: A. error for a step input is always zero B. error for a velocity input is always zero C. input for acceleration input is always non-zero D. (a) and (c) E. None of the above

error for a step input is always zero
error for a velocity input is always zero
input for acceleration input is always non-zero
(a) and (c) E. None of the above

The correct answer is: E. None of the above

A type 0 system is a control system that has a zero derivative of the transfer function at the origin. This means that the system has no steady-state error for a step input. However, the system will have a steady-state error for a velocity input. The input for an acceleration input is always non-zero for any type of system.

Here is a more detailed explanation of each option:

  • Option A: The steady-state error for a step input is always zero. This is true for a type 1 system, but not for a type 0 system.
  • Option B: The steady-state error for a velocity input is always zero. This is true for a type 2 system, but not for a type 0 system.
  • Option C: The input for acceleration input is always non-zero. This is true for any type of system.
  • Option D: Both options A and C are true. This is not true, as explained above.
  • Option E: None of the above. This is the correct answer.
