Chapter 1, Problem 15P
In the Case Study of Section 1.4. an antenna azimuth angle is controlled, and its corresponding block diagram is shown in Figure 1.8(d) in the text. There, the sensor used to measure the antenna's azimuth angle is a potentiometer.
- Modify the block diagram if the sensor used to measure the antenna's angle is an accelerometer.
- Modify the block diagram if the sensor used to measure the antenna's angle is a gyroscope.

The image below depicts one section of a cam shaft which opens a valve to release the pressure in the combustion chamber. In order to synchronize the position of the piston and the release of the valve, there is a sensor that measures the position of the camshaft. The sensor can determine when point a is 0.672 in. to the right of the center of the camshaft and 0.672 in. above the center of the camshaft. In a four stroke engine the crank shaft, which is connected to the pistons, turns twice for every turn of the camshaft. At cruising speed the crank shaft turns at 3,000 rotations per minute (rpm) which means that the camshaft turns at 1,500 rpm or 25 revolutions per second (rps). After 0.825 seconds, where would point a be in relation to the center of the camshaft?* Answer options are: (-0.589,0),(0.116, -0.316), (0,-0.95),(0.86,-0.315),(0.431,0), none of these are correct. Please be sure to show your steps.

Example 1.1 Figure 1.5 shows the block diagram of a closed-loop flow control system. Identify the following elements: (a) the sensor, (b) the transducer, (c) the actuator, (d) the transmitter, (e) the controller, (f) the manipulated variable, and (g) the measured variable.
In the figure above, the (a) sensor is labeled as the pressure cell. The (b) transducer is labeled as the converter. However, there are two converters: one for converting pressure to current, and another converting current to pressure for operating the actuator. The (c) actuator is labeled as the pneumatic valve. The (d) transmitter is labeled as the line driver. The (e) controller is labeled as the PLC. The (f) manipulated variable is labeled as the pressure developed by the fluid flowing through the orifice plate. The (g) measured variable is the flow rate of the liquid.
