Exam 7: Embedded Microcontrollers, Open and Closed Loop Process Control

Match the definition with the correct tuning method listed . Methods can be used as often as necessary. -Works with process that have a either a fast or slow response for the process variable when a set point change is made.

Dead time delay is the time delay between the start of the transient response and the time that steady state response starts.

Match the definition with the correct tuning method listed . Methods can be used as often as necessary. -Uses parameters like dead time, change in controller output, and slope of the transient curve to calculate tuning parameters.

Fuzzy logic controllers use rules and reasoning principles similar to human problem solving in the solution of control problems.

Select the statement below that is the definition of a minimum integral of the absolute error response curve.

Match the definition with the correct tuning method listed . Methods can be used as often as necessary. -Requires fine tuning of the tuning parameters after initial calculations if the process is a second order lag type system.

Parallel I/O is referred to as GPIO.

The synchronous communication port on a microcontroller is used for servicing and testing.

In -circuit emulators provide a quick, accurate and inexpensive method of debugging.

The on -off controller's output is either 0 or 100 percent on either side of the zero error value.

PWM is one type of controller output; the other is gain -error product.

Analog derivative controllers have a capacitor in the feedback path and integral controllers have a capacitor in the input path of the amplifier.

Match the definition with the correct tuning method listed . Methods can be used as often as necessary. -The period of the system oscillation is used in the tuning parameter equations.

When a bump test is performed you get a process response curve that can be used to check proper tuning of a process variable.

The content of a ROM is sometimes called firmware because it contains the program.

March the feature to its language. -Simple development

Proportional band is the total range of the error signal that causes the final control element to go through its full range.

MATCHING. Choose the item in column 2 that best matches each item in column 1. Match the process control term with the correct definition of the term. Definitions may be used more than once. -Disturbance

Digital controllers calculate the output at time intervals called processor recalculation time.

Select the statement below that is the definition of a quarter amplitude decay response curve.
