Define feedforward **system**, define absolute stable...
Commonly, ffwd **system** means an open loop **control** **system** without any feed back. As far as I'm aware of, "absolute **stability**" is an algebraic rather than **control** theory term. In so far I'm not sure what's it's expected to mean in this (...)

Is the above rule a sufficient condition for MIMO feedback **stability**?You can not understand contents I posted at all.
Modern **control** theory is surely useful for judging **stability** of MIMO **system**.
Your complex filter is formulated by using state space variable equations.
So modern **control** theory is (...)

PID **control** needs specs to define , **system** step error response, overshoot under worst case gain and time lag and rate of change of disturbance response Impulse error response ( like opening door on ice cold day)
For **stability** , frequency / phase margin is used to determine correct feedback signal conditioning and gain to optimize speed, (...)

Can you help me compare these results? They're the simulations of a closed loop **system** . When we change the poles, (in this case, there are 4 poles), the response **system** also changes. The 4 poles involves 2 complex numbers and 2 integers, but I don't see the relationship between the poles and the response. I don't see an exact description. I mean,

Whats the need of studying **control** **system** in electronics?
Feedback is one of the basic principles applied in electronics.
Connected with the principle of feedback are the terms "feedback loop", "loop gain", "closed-loop gain", "**stability**", "**stability** margin".
The theory behind all these parameters is provided by s

i know for **stability** we need positive PM GM . that means at -180 degree gain should be negative(in decibels) for stable **system**s . From where this arrives i mean why -180 ?? i read somewhere that after -180 degree NEGATIVE FEEDBACK BECOMES POSITIVE FEEDBACK and if at that time gain >1 than **system** will oscillate and become unstable ?? why (...)

Hi,
I am interested to know,
which plot(Ny, Bode, Nichols, RH, etc) of **control** **system**s will be more accurate and absolute in describing **stability** (Open loop and for closed loop if compensator is added) of a **system** and why .......?
*All plots are (resp. can be) "accurate".
*However, if you are interested in sta

what is meant by impulse response? why we use it to study to character of the signal that is study the linearity,**stability** etc? why it is called ideal **system** to study?
plz help i hav read signa sys,**control** etc but i hav yet not understand this problem

hello all my friend!
I am learning about of temperature **control** using micro**control**ler. I have a problem to **control** the **stability** of the **system** in desire set point temperature using PID **control** method. How to find or simulate a K,Td and Ti parameters of K-type thermocouple in Ziegler (...)

Hi all ,
Can any one give me the references for doing the **stability** analysis if there are multiple feedback loops (i have two feedback loops in my circuit ) in circuit ... Thanks in advance

I think you should study theory of **control**. because you will meet the question of **stability** when you do dc/dc. The most dc/dc is a nonliear **system**, and is feedback loop.

Have anyone have the method for look to the Routh table for the **stability** in **control** **system**. for know about the left half-plane (lhp), right half-plane(rhp) n jω? if u have can u upload for me? thanks!

Who can tell me what is **stability**? I often see the right-half-plane used to determine whether a circuit is stable. Who can tell me how to use this technology and what it is?

Without it **control** **system** will paralise itself. It heavily depends on Transfer Function.. for **stability** purpose....

Hi ,
In this case u need not worry about the loop gain as the second pole occurs after unity gain freq. First and foremost is that **system** with two poles (one zero also-so need not worry at all) wont oscillate as the **system** can oscillate only on theoritical ∞ freq.
Minimum of three poles shd be there to cause a **stability** (...)

Can anything be decisively said about Phase Margin in freq domain on seeing the percentage overshoot OR settling time in time domain?
thanks

One problem with the feedback approach is the nonlinearity and hysteresis involved in the mechanical portion. Even very small amounts of these will cause **stability** problems in the **control** **system**.
In the stepper motor approach you can gear down the drive so that the increments of motion are smaller than the specification for surface (...)
