Control Technique
|
|
|
| |
Your choices are...
|
|
|
| |
Limit / Set Point Control
|
|
Limit control indicates "set points", or limits, that when reached, send a signal to stop or start a process variable. This "off-on" or "bang-bang" control is a fairly simple type of control.
|
| |
Linear Control
|
|
Linear control is simply matching a variable input signal with a correspondingly variable control signal. Signal conditioning, filtering, and amplification may occur to produce the proper output control signal.
|
| |
Feedforward Control
|
|
Direct control compensation from the reference signal. This technique does not require a sensor; it may be open-loop or in conjunction with more advanced PID control.
|
| |
PID Control
|
|
Proportional, Integral, and Derivative (PID) control; requires real-time system feedback. This is a more sophisticated control that monitors the error between desired variable value and the actual, and adjusts control accordingly (proportional). The derivative and integral can provide further control refinement by incorporating variables like rate of change of error to tune the control signal. While sophisticated, PID control needs to be tuned to prevent noisy operation and accurate process control.
|
| |
Fuzzy Logic
|
|
Fuzzy logic is a type of logic in which variables can have imprecise values (as in partial truth) rather than a binary status (completely true or completely false). Information and rules can be inexact and calculations can be made on these imprecise values.
|
| |
Advanced / Nonlinear Control
|
|
Unlisted control algorithm such as neural networking, adaptive gain, or emerging algorithms.
|
| |
Other
|
|
Unlisted or specialized control algorithm or technique.
