Based on my increasing understanding, I'd like to reframe my question. Please assume a very fast process time constant and almost no dead time. Let’s leave loop update time and task scan rate out of this . . . I know how to use those and I know how to set them when I have specified how...

I am still hoping for a precise answer to my first question about the relationship between response time and RPI and/or RTS. Or to make it a less ControlLogix specific question, what how often should the analog input channel sample relative to the response time of the transmitter?

I'm not sure from your question if this is a homework problem...a math exercise, or a real-world problem. If it is a real world problem then you can set up a PID in a controller (DCS or PLC) without modeling very much. Your math might be useful to calculate process time constant and deadtime...

I’m trying to improve a PID loop and am examining the analog input. I have one very specific question then a few more that would help me do this myself next time. In case it is helpful, I'm using a ControlLogix system. 1. My most specific question is, given that response time = 250millisec on...

I didn’t discuss synchronicity because we don’t control the synchronizing relay. The system that provides us the analog signals containing kW and PF (and KVAR which I don't use) has a synchronizing relay. Our job is simply to control once online. In light of that, do you think my control...

Based on thinking about the information provided so far, I’d like to ask you to help me validate two primary assumptions. Can you please tell me if you know or don't know if the assumptions below are correct? 1.) Before connecting a synchronous generator to a utility power grid, we believe...

Mr. Beach I thank you for the comment. The few hours I spent designing this were very enjoyable and so even if I’m reinventing the wheel it is no waste. But I’m interested to know more about the algorithm(s) you mentioned, and compare them to my design. Will you please elaborate on them so I can...

I am tasked with designing a PID control strategy for a system that will use fluid power to turn the shaft of a synchronous generator. My question is whether my planned control strategy will work, and specifically, will my two PID loops interact and therefore not work well. The generator will...
