Chapter 10, Problem 22RQ
Program Plan Intro
Proportional Integral Derivative (PID) control:
- The PID control refers to a feedback control method.
- It performs the combined actions of proportional, integral, and derivative controls.
- It is one of the most widely used process controllers.
- The PID control is used to maintain a process variable within the limits of a specified set point. These process variables can be temperature, flow, level, or speed.
- It also allows the control process operations to take place outside the Central Processing Unit (CPU), which in fact, greatly reduces the additional burden of CPU.

- (Electrical eng.) a. Write, compile, and run a C++ program that calculates and displays the value of the current flowing through an RC circuit (see Figure 3.19). The circuit consists of a battery connected in a series to a switch, a resistor, and a capacitor. When the switch is closed, the current, i, flowing through the circuit is given by this formula: i=(EIR)et/RC Eisthevoltageofthebatteryinvolts.Risthevalueoftheresistorinohms.Cisthevalueofthecapacitorinfarads.tisthetimeinsecondsaftertheswitchisclosed.eisEulersnumber,whichis2.71828( roundedtofivedecimalplaces). Using this formula, write, compile, and run a C++ program to determine the voltage across the capacitor shown in Figure 3.19 when t is 0.31 seconds. (Note: The value of RC is referred to as the system’s time constant.) The program should prompt the user to enter appropriate values and use input statements to accept the data. In constructing the prompts, use statements such as “Enter the voltage of the battery.” Verify your program’s operation by calculating by hand the current for the following test data: Testdataset1:Voltage=20volts,R=10ohms,RC=0.044,t=0.023secondsTestdataset2:Voltage=35volts,R=10ohms,RC=0.16,t=0.067seconds b.
