For the same two responses below (System A – green (gradually becomes parallel to the blue line as time increases), System B – purple): If eliminating steady-state error matters more than response speed, System A is the preferred design.

Because a sensor is present in the loop, noise entering the feedback path has no effect on the output of a closed-loop system.

Adding an output sensor and a comparison (summing) junction converts an open-loop architecture into a closed-loop architecture.

An open-loop system can correct for a disturbance that is injected between its controller and the plant.

A lawn-sprinkler timer that waters every morning for 20 minutes, regardless of soil moisture, is a closed-loop system.

The three primary objectives of control-system analysis and design are _____.

The main penalties for adding feedback to a control system are increased cost and complexity, such as the additional sensors and comparison hardware.
