Hello,

For the Proportional Term, I think it's wrong in the graph of "Change of response for varying Kp". The black curve with smaller oscillation should have a smaller proportional gain Kp. The red curve with bigger oscillation should have a bigger proportional gain Kp. But in the graph, it seems wrong way round. So by my understanding, the black curve should have Kp=0.5 and the red curve should have Kp=2. Am I right?

Many Thanks,

Li

The page has it correct. A higher proportional gain will increase response time. Notice how the black curve approaches the command at a faster rate then the others.

On the other hand the red curve, with the smallest gain out of the 3, has the slowest response and thus the largest overshoot.

Bmike210 is correct. Thank you. Bsodmike (talk) 18:15, 31 August 2009 (UTC)[reply]
