- 1an arrangement, set, or collection of things or related in such a manner as to form an entirety or wholesystem
- 2an arrangement of physical components connected or related un such a manner as to form and/or act as an entire unitsystem
- 3is an arrangement of physical components connected or related in such a manner as to command, direct, or regulate itself or another systemcontrol system
- 4the stimulus, excitation or command applied to a control system, typically from an external energy source, usually in order to produce a specified response from the control systeminput
- 5actual response obtained from a control systemoutput
- 6may or may not be equal to the specified response implied by the inputoutput
- 7a control system that is part of a larger system, its inputs and outputs may then be internal variables of the larger systemsubsystem/control subsystem
- 8the quantity responsible for activating the system to produce the outputcontrol action
- 9one in which the control action is independent of the outputopen-loop control system
- 10one in which the control action is somehow dependent on the outputclosed-loop control system

- 14a concept to be subsequently discussed in detailinstability
- 15any physical system which does not automatically correct for variation in its inputopen-loop
- 16control system that is sensitive to disturbancesopen-loop
- 17control system that does not measure anythingopen-loop
- 18Any physical system which does automatically correct for variation in its outputclosed-loop
- 19The output is constantly monitored and adjusted to the required value by the systemclosed-loop
- 20that property of a closed-loop system which permits the output t (controlled variable) to be compared with the input to the system so that appropriate action may be formedfeedback
- 21closed-loop control systems are more commonly called ________feedback control systems
- 22shorthand, pictorial representation of the cause-and-effect relationship between the input and output of a physical system.block diagram
