Interesting, I didn’t know there was anything except PP. I was thinking the other night of making my own and perhaps competing with PP. Not all PID loops are the same. Oh PID refers to Proportional, Integral and Derivative control. Basically they are the three different constants used to tune a control loop. The loop being the relationship between input (speed) and output (throttle) with respect to the set point (desired speed). So, pending the equation used and the efficiency of the program the results/precision/smoothness of the loop can change. However, the constants can usually be tweaked enough to get all the loops to act similar. But even then, every real application is different, even with the same boat/motor. That’s why you see some guys complain about varying speeds they get with PP. With a few hours and a little bit of patience I’m sure you could tune every unit hold speed very accurately, including your EZ unit. Hmm…maybe there is hope for some money out of this. Anyone got a bugger PP system out there? I know a Controls Engineer with a lot of free time. Just another pipe dream I suppose. (Message edited by derby on June 27, 2006)
