Disadvantage of Compensator
- A certain amount of attenuation is added to the system with the addition of the lead network. Therefore, there needs to be an additional gain improvement to make up for the attenuation. However, when gain increases, more elements become necessary.
- This results in increased weight and space in addition to increased expense.
- Because the lead network lessens overshoot, undershoot circumstances are increased. The system becomes conditionally stable as a result occasionally.
- A lead angle of roughly 60° is provided by a single lead network. Therefore, a multiple lead compensator needs to be added to the system in order to accommodate the greater lead of around 70 to 90°.
- The lead network expands its bandwidth, but as it does so, the system is more vulnerable to noise.
Compensators
All of the topics covered in the Control System Tutorial, including the Introduction to Control Systems, Classification, Transfer Function, Signal Flow Graphs, Mason Gain Formula, Block Diagram, State Space Model, and more, are included in our tutorial.
The compensator is an extra part that is introduced to the control system’s structure throughout its redesign. It is included in order to make up for the system’s poor performance. A compensator can be mechanical, electrical, hydraulic, or any combination of these.
