By adding poles and zeros to the transfer function of a system we can affect its root locus and also the stability. If we add a valid zero to the T.F. it will shift the root locus towards left side of the s-plane and thus the stability increases. And if we add a valid pole reverse process of that of adding zero occurs...

What is nyquist set?
The Nyquist stability criterion, named after Harry Nyquist, provides a simple test for stability of a closed-loop control system by examining the open-loop system's Nyquist plot. Under many circumstances, stability of the closed-loop control system may be determined directly by computing the poles of the closed-loop transfer function. In contrast, the Nyquist stability criterion allows stability to be determined without computing the closed-loop poles
Can we know the stability from Bode plot?
It has been awhile for me, but if all of the poles are to the left of the vertical axis, then it will be stable. Any poles on the vertical, or to the right, and it will be unstable.
You can determine quickly the effect of adding poles and zeros by?
Root locus
What is timber defects like shake checking wane and split?
Checking is a natural occurrence in lumber and poles that happens when the sapwood of a tree dries around the heartwood. Usually, it does not have an affect in the structural value.
How many poles are within a DC motor?
It depends on the motor. They can be purchased with different numbers of poles. The number of poles mainly changes the speed of the motor.
What is the meaning of poles and zeros?
poles are the plot of the transfer function of a system on the left side of the origin, in s-plane. zeroes are the right side plot. poles and zeroes specifies the absolute stability of the system.. they also gives the observability and controllability of the system..

What does the root locus mean?
The root locus represents the movement of the poles of a system as a parameter is varied. It helps in analyzing the stability and dynamic response of a system. By plotting the locations of the poles in the complex plane, engineers can understand the behavior of the system and design appropriate control strategies.
How do the poles on a magnet affect the interaction of two magnects?
the poles effect it beacuse it can attract the poles
What are the poles on the net called?
The poles on a net are typically known as "posts" or "supports." They provide the structure and stability needed to keep the net in place.
Can we know the stability from Bode plot?
It has been awhile for me, but if all of the poles are to the left of the vertical axis, then it will be stable. Any poles on the vertical, or to the right, and it will be unstable.
What is arbitrary pole placement?
Arbitrary pole placement refers to the process of selecting the locations of the poles of a system to achieve desired dynamic behavior. By choosing the pole locations, engineers can design the system to have specific characteristics, such as stability, performance, and response time. The poles can be placed using various control techniques to meet the desired requirements.

Root locus
What are poles in electrical control system?
poles are the wires and where they are connected
What are the types of system stability analysis?
We can classify the systems based on stability as follows. Absolutely stable system Conditionally stable system Marginally stable system Absolutely Stable System If the system is stable for all the range of system component values, then it is known as the absolutely stable system. The open loop control system is absolutely stable if all the poles of the open loop transfer function present in left half of āsā plane. Similarly, the closed loop control system is absolutely stable if all the poles of the closed loop transfer function present in the left half of the āsā plane. Conditionally Stable System If the system is stable for a certain range of system component values, then it is known as conditionally stable system. Marginally Stable System If the system is stable by producing an output signal with constant amplitude and constant frequency of oscillations for bounded input, then it is known as marginally stable system. The open loop control system is marginally stable if any two poles of the open loop transfer function is present on the imaginary axis. Similarly, the closed loop control system is marginally stable if any two poles of the closed loop transfer function is present on the imaginary axis.
What is meant by poles?
River rafts are often conveyed by poling. See the definition of 'poling' at the Related Link, listed below:
If Antarctica is located where Europe is where are the north and south poles?
The North and South Poles would be located at the same positions as they are currently, with the North Pole at the top of the Earth and the South Pole at the bottom. Antarctica's position would not affect the locations of the poles.
