Chapter 11
1 Assume that Figure 11.25(a) is the response curve of a control system to a step function. Determine the following parameters: rise time, overshoot, and settling time.
2 A robot arm was commanded to go to a new position. Its response was recorded and is shown in Figure 11.41. Determine the rise time, overshoot, settling time, and steady-state error of the response, approximately.
6 In your own words, explain the principle of proportional control.
8 A proportional controller for a rotating antenna has a gain KP of 5 in · oz/deg. The antenna was initially pointing due south but was then commanded to point southeast.
12 A proportional control system is to be used to control the wing flaps of a jet airplane. The wind load is expected to cause as much as 600 in · lb of torque. The system should be able to keep the flaps to within 5° of the set point. Find the gain KP necessary to meet the requirements.
19 Explain how derivative feedback makes a control system more responsive to rapid change and how it reduces overshoot.
