Lesson 1 - Introduction Flashcards
is an arrangement of physical components connected or related in such a manner as to command, direct, or regulate itself or another system.
Control System
is an arrangement of physical components connected or related in such a manner as to command, direct, or regulate itself or another system.
Control Systems
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
Actual Response obtained from a control system. It may or may not be equal to the specified response implied by the input
Output
The input and output can also be a part of a larger system, in which case it is called a
Subsystem or Control Subsystem
is the system,subsystem, process, or object controlled by the feedback control system
Plant (process or controlled system)
output variable of the plant
Controlled output
transmission path from the summing point to the controlled output.
Forward Path
control action is independent of the output
Open-Loop Systems
control action is somehow dependent on the output. Commonly called feedback control system
Closed-Loop Systems
It is the central task of an engineer. It is a complex process in which creativity and analysis play major role.
Engineering Design
is the process of conceiving or inventing the forms, parts, and details of a system to achieve a specified purpose.
Design
is the process by which a system’s performance is determined
Analysis
is the process by which a system’s performance is created or changed.
Design
This response resembles the input and is usually what remains after the transients have decayed to zero.
Steady-State Response
This type of response is important. In the case of the Elevator, a slow transient response makes passengers impatient. Whereas excess in rapid response makes them uncomfortable
Transient
Analysis and Design Objectives
Transient Response
➢Steady-State Response
➢Stability
➢Other considerations:
•Hardware Selection (e.g. sensor’s accuracy, motor size)
•Finances (e.g. budget allocation, if one of a kind vs many copies)
•Robust (sensitive to changes)
is as much a concept as it is a physical system. In essence, the concept is to deliver power more reliably and efficiently while remaining environmentally friendly, economical, and safe.
Smart Grid
The five key technologies required to implement a successful modern smart grid include
• (i) integrated communications,
• (ii) sensing and measurements,
•(iii) advanced components,
• (iv) advanced control methods, and
•(v) improved interfaces and decision support.

What is control system?
set of mechanical or electronic devices that regulates other devices or systems by way of control loops. (Nasa sayo ano naman basta masaya ka)

For you what is control systems?
Nasa sayo naman yan
device that makes possible the execution of the control action on the plant, so that the output of the plant follows the reference input.
Actuator
used to change
Output signal so it is compatible with the reference input.
Transducer
