(A) Proportional-Integral-Difference (B) Proportional-Integral-Derivative (C) Proportional-Independent-Derivative (D) Proportional-Inductive-Derivative 2. What is the primary function of the proportional (P) term in a PID controller? (A) To integrate past errors (B) To eliminate steady-state error (C) To predict future errors (D) To adjust the output based on the magnitude of the error 3. What does the integral (I) term in a PID controller do? (A) It corrects the system based on the current error (B) It adjusts the system based on the rate of error change (C) It sums up past errors to eliminate steady-state error (D) It predicts future errors based on current data 4. What is the purpose of the derivative (D) term in a PID controller? (A) To adjust the output based on the magnitude of the error (B) To sum up past errors (C) To predict future errors based on the rate of error change (D) To eliminate steady-state error 5. What is “PID tuning”? (A) The process of calculating steady-state error (B) The process of measuring system output (C) The process of adjusting the proportional, integral, and derivative gains to achieve desired performance (D) The process of designing the system’s feedback loop 6. What effect does increasing the proportional gain (Kp) have on a PID controller? (A) It increases the system’s stability margin (B) It decreases the system’s response time (C) It decreases the steady-state error but may increase overshoot and oscillations (D) It eliminates the need for integral and derivative terms 7. How does increasing the integral gain (Ki) affect the PID controller? (A) It eliminates the need for proportional gain (B) It improves the system’s response time (C) It decreases the rate of error change (D) It reduces steady-state error but can cause increased overshoot and oscillations 8. What effect does increasing the derivative gain (Kd) have on a PID controller? (A) It decreases the system’s response time (B) It increases the steady-state error (C) It eliminates the need for proportional and integral gains (D) It improves the stability and reduces overshoot by responding to the rate of change of the error 9. In a PID controller, what does “derivative kick” refer to? (A) An undesirable spike in the control output caused by sudden changes in the error signal (B) The delay in the feedback loop (C) The steady-state error in the system (D) The time required for the controller to stabilize 10. What is “integral windup” in a PID controller? (A) The initial response time of the system (B) The delay in the system response (C) The condition where the integral term accumulates excessively due to prolonged large errors, leading to overshoot (D) The effect of noise on the integral term
