A continuous-time unity-gain (tracking) feedback system has a forward-path transfer function with exactly one pole at the origin of the s-plane.


(a) Describe in as much detail as possible the steady-state error signal in response to a step excitation.

(b) Describe in as much detail as possible the steady-state error signal in response to a ramp excitation.


(a) Describe in as much detail as possible the steady-state error signal in response to a step excitation.

This is a type one system and the steady-state error for step excitation will be zero.

(b) Describe in as much detail as possible the steady-state error signal in response to a ramp excitation.

For a type one system in response to a ramp excitation, the steady-error will be non-zero, but finite.

McMillan Company manufactures electronic flow sensors that are designed as an alternative to ball-and-tube rotometers. The company recently spent $3 million to increase the capacity of an existing production line. If the extra revenue generated by the expansion amounts to $200,000 per month, how long will it take for the company to recover its investment at an interest rate of 12% per year, compounded monthly? Solve using (a) tabulated factors and (b) a spreadsheet or calculator.

The pitch of a roof refers to its “steepness” and is expressed in terms of the number of inches the roof rises for each 12 inches of run. For example, an 8-12 pitch means that the roof rises 8 inches vertically for each 12 inches of horizontal run. What is the slope of a roof with an 8-12 pitch?
