That's a mathematical model you presented (and not clear if you mean to be in discrete or continuous time?) and isn't remotely close to what the average person would understand from the word "craft".I'm shouldn't doubt that the average person might not understand his "craft" from my mathematical model.:=) However, I submit that it is accurate in this instance. All it says is that the control system knows the speed and location of each train within its jurisdiction and issues commands to each train as to what the desired speed should be. I think you have said essentially the same thing in a subsequent post. In all your years in industrial controls, did you not once find a real-world situation that departed from textbook analysis? Many textbooks will make simplifications to illustrate only one or two principles in an example. If your question had been: have I ever encounted a situation wherein Maxwell's equations or Newton's laws were violated, then the answer is no. Have you encountered such situations? |
