TERMS Flashcards
. Concerned with understanding and controlling segments of their environment, often called systems, to provide useful economic products for society
Control Systems Engineer
It is based on the foundations of feedback theory and linear system analysis, and it integrates the concepts of network theory and communication theory.
Control Engineering or control Systems
Is a set of mechanical or electronic devices that regulates other devices or systems by way of control loops.
Control System
. Usually taken to mean regulate, direct, or command
Control
Is an arrangement of physical components connected or related in such a manner as to form and/or act as an entire unit.
System
Is the actual response obtained from a control system.
Output
Is the 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 system
Input
. A control system involve human effort and rely on personal skills.
Manual Processes
. One in which the control action is independent of the output.
open-loop control system
A system that utilizes programming logic to automate the operation of the instrumentation and systems so as to produce the operational results.
Automatic Control System
. Often denoted as u(t), is a fundamental signal in signal processing and control theory.
unit step function
. Fundamental signal in signal processing and control theory represents a linearly increasing signal
ramp
. A signal whose magnitude grows or decays exponentially with time
exponential signal
It represents a smooth oscillation that varies sinusoidally with time.
sinusoidal wave
Used to represent various periodic phenomena such as alternating current (AC) in electrical circuits, sound waves, vibrations, and electromagnetic waves
Cosine Wave
It is the transformation from the s-domain into the t- domain.
Inverse Laplace Transform
It transforms a problem from the real variable time domain into the complex variable s-domain.
Laplace transform
. Allow separation of the input, system, and output into three separate and distinct parts. The function will also allow us to algebraically combine mathematical representations of subsystems to yield a total system representation.
transfer function
. Is a mechanical element that can be deformed by an external force such that the deformation is directly proportional to the force applied to it.
Translational Spring
. Is a mechanical device often used in mechanical systems to provide damping or resistance to motion.
