Controller Design Techniques : |
| |
For linear systems: |
|
Root locus . |
|
Bode plot. |
|
Nyquist plot.
|
| |
(All the three above mentioned are graphical techniques)
|
|
State space design tools.
|
| |
For Non-linear systems:
|
|
Lyapunov method. |
|
Singular perturbation. |
|
Feedback linearization |
| |
Controller Implementation: |
| |
Analog domain
: |
|
Use of Electronic circuits (main element is op-amp. ) |
| |
Digital domain: |
|
In this computer or micro-controller is used as a controller.. |
|
In case of Computer as a controller, sensors & actuators handle analog signals while
Computer handles digital signals.
Conversion from Analog to Digital and Digital to Analog is necessary.It is done by using Analog to digital & digital to analog converter. |
