Hi
Does anyone have "master password" required to download docs from Eurotherm website. furthermore any advise in working with Eurotherm 2604 will be acknowledged.
Thanks

I suggest you to check the website of apexmicrotech which is a producer of transducer drivers. for example pa241 and pa98 are two candidates.

for fix value of all the parameters except v you may calculate Cp and λ for different value of v. for this purpose you can diffine v as a vector with your specific values. then calculate Cp and λ for those values of v. then just you need to use plot command.
about your second question I can not...

Holes are virtual consept to simplify our model of phenomena. we can say holes are the virtual particles that carry the positive current.
Mathematically every system can be modeled linear or nonlinear. for nonlinear systems the relation between output and input or output and states are not linear. there are several way to simplify the nonlinear equations or find a more simple method to get the desired data. sometimes we use...
To design and build a new power supply with this specification is easier than to change a pc power supply for your purpose. as you know pc supplies are constant power supplies and there is no unique design for them. just may be you can dis assemble the components and use some of them in your disign
High loop gain by itself is not the condition of oscilation, dont forget that the overal system transfer function is equal to A/(1+AB), so when AB>>1 we can say that overall system transfer function is 1/B.
the condition of oscilation is magnitude equal 1 and phase equal 360 (or 180 if you dont...
Re: Sampling Time
If your sampling freq is 1Mhz, so your sampling time is 1e-6, you should use zero order hold after your continuoes signal and then your discrte time integrator.
for example I have simulated following scheme. you can see the result and compare the discrete and continuos...
Re: Sampling Time
you should use zero order hold to discretize your system, therefore the sampling time introduce in the transfer function of your system, for an integrator the discretized system with zero order hold is
Ts z^{-1}/(1-z^{-1})
where Ts is the sampling period
Re: Zeros in FIR filter
zero on the unit circle means your system (filter) will cancel out any signal with that frequency completly . because the transfer function of filter at that frequency is zero.
the zeros outside the unit circle are non minimum phase zeros and inside the unit circle are...
Re: DC MOTOR RPM CONTROL
Hi
I am not sure that your system can work with fast command change, as the other friend mentioned, the problem of aliasing is the first problem of your system. the second one there is no any sence of error amplituse in your system and so there is no difference between...
pwm dc dc chopper
In a dc-dc converter, there is a fixed and not very regulated voltage (say the rectifier voltage) in one side, on the other side we want to have a regulated and variable dc voltage which for example we can use for controling a DC motor.
a chopper that chop the primary dc...
