What process control system control mode is most likely to have steady-state error (also known as offset or residual error)?

🔍 Key Concepts

• Steady-state (offset) error in control systems • How integral action affects long-term error • Differences between P, PI, PD, and PID control modes

💭 Think About

• Which control modes include an action that keeps accumulating error over time until the difference is driven to zero? • Which control mode(s) react only to the present error, and not to the accumulated past error? • How does derivative action (rate of change) influence steady-state error compared with proportional and integral actions?

✅ Before You Answer

• Identify which choices include integral control and which do not • Recall: integral action is specifically designed to eliminate steady-state error • Consider which mode is most likely to leave a constant offset between setpoint and actual value when the system has settled
