Control and Correlation An Article slimemoldtimemold.com In any control system that is functioning properly, the methods used to control a signal won’t be correlated with the signal they’re controlling. Worse, there will be several variables that DO show relationships, and may give the wrong impression. You’re looking at variables A, B, C, and D. You see that when A goes up, so does B. When A goes down, C goes up. D never changes and isn’t related to anything else — must not be important, certainly not related to the rest of the system. But of course, A is the angle of the road, B is the gas pedal, C is the brake pedal, and D is the speed of the car. statisticsfeedbackcontrol
