    Which factor of PID accounts for feedback delay?

    This is software based controller to control the rate of packet transmission for network. The delay is the round trip time for the packet to reach the other end and a response to come back.

    Which factor of PID accounts for feedback delay?

    When I have a PID loop to control a process where there is a delay between setting the set point value and when it can be seen to have an effect on the measure point. which of the three inputs adjusts for that, proportional, integral, or differential? How would I tune my PID loop factors to...

    PID for controlling transmission rate

    > If you have a way of detecting errors (and can therefore measure the error rate), and don't care about trying to retransmit data, or keep packets in order, and really want to try with a PI controller, then I would try the following: < Excellent, that fits the bill, thanks! >SP (Setpoint)...

    PID for controlling transmission rate

    > ... the first thing you have to determine is what is your target value ... < I want to maximize the transmission speed without lots of dropped packets. For example, less than 2% of packets being dropped. So I do not know what my target value is, and it will change over time. This is...
