the output waveform for step response is the paramater you are trying to control. you have not given enough details exactly what you are trying to do so I assume you are trying to control motor current through PWM then you should apply various step inputs of duty (changing duty from one value...
Feed Forward loop is implemented in any system to compensate for the known variations
For Example - (which I have used) - In case when we control current of solenoid by PWM, the current will vary for particular duty depending on the supply voltage, so we measure and compensate for supply...
A contest for Indian Robot hobbyists, to win a H8/3664 Microcontroller based Robot Control Board, which has 2 H-Bridges (5A capacity each) and an IR Modulator has been announced on https://www.icesociety.org

It doesnot assume heatsink temperature to be 10C
it assumes difference between ambient temperature and heatsink temperature to be 10C so if ambient is 70C then heatsink will be at 80C
So it doesnot assume heatsink thermal resistance to be 0 (if you calculate from power and assumed...
The guy who has written the wiki has consider the heat resistance of the heat sink by considering deltaTHS of 10C. and this is the normal way of calculations because from heat sink to ambient the heat dissipation is due to radiation which is normally determined by experimentation rather than...
In case of automotive applications
Mostly in Japan, we use low side current sensing, while in US and Europe high side current sensing is used.
In case of High side current sensing, the common mode voltage reference of the opamp input needs to be high. In case of low side current sensing the...
Hi all,
We are testing the engineering portal at
**broken link removed**
Any help in testing the portal before launch will be appreciated
The present features we are testing are
**broken link removed**
1) Forum - like this one (but I think I will start that forum from scratch and...
Hi all,
I am working on a new engineering portal and will like your help for development of the same. My present forum is at www.coepinstru.org/forum
The new engineering portal will be for all the engineering branches with more focus on Instrumentation and Control Engineering.
Right now I...
I have a forum running at www.coepinstru.org/forum
I am already working on making that forum into a complete engineering portal
If you need anykinda help in particular then do let me know
I have also bought new domain name and webspace
Can I know which webhost you are using?
**broken link removed**
This software is based on asp and java
I have used this software in my forum **broken link removed**
At the bottom of the Index page you can see the option of chat room
Well I was not talking about ACK bit here, I was talking about the full response like from the receiver
Like for example A sends a data read command to B, then A expects some data from B in a certain time frame depending on the time cycle of command and if it does not get the response then it...
Hi,
just for your information
when A device sends a command over CAN line to another device it accepts a response from the receiving device
you will have to check since there will be an intermediate device in the communication path there will be some delay in this response and depending on...
Another Idea will be to use a microcontroller with two CAN channels ( I dont know if PIC ICs come with two CAN channels, but microcontrollers from freescale and renesas are available)
Connect one channle to device A and other to Device B and in your software simply pass on the data form...
