When 'reset' action is added to proportional action, the proportional action __________.

🔍 Key Concepts

• Proportional (P) control – how controller output changes in proportion to the present error • Reset (Integral, I) action – how the controller responds to sustained (steady‑state) error over time • Behavior of a PI controller during increasing vs. decreasing error transients

💭 Think About

• Think about what proportional action does when the error is getting larger versus when it is getting smaller. Does it push the output in the same direction as the reset action, or counteract it? • Ask yourself: during an increasing error transient, how does the integral (reset) term change, and how does the proportional term change? Are they acting together or against each other? • Consider a situation where the error is decreasing after a disturbance. How would proportional and reset actions each behave, and what combined effect would you expect?

✅ Before You Answer

• Be clear that reset = integral action, which accumulates error over time, not just the instantaneous value • Distinguish between transient (changing) error and steady‑state (constant) error and how each term responds • Check whether proportional and reset outputs have the same sign or opposite signs when the error is increasing versus when it is decreasing
