In the context of PID control, what is the primary consequence of an excessively high derivative gain ($K_d$) in a noisy process, and how does it manifest in the controller's output?
Question 2
Consider a chemical reactor with multiple interacting process variables (e.g., temperature, concentration, pressure). Which advanced control strategy is most appropriate for handling these interactions and achieving optimal performance across all controlled variables simultaneously?
Question 3
A chemical process exhibits a non-minimum phase response. Which of the following statements accurately describes a characteristic of such a system and its implication for control loop design?
Question 4
In the context of control loop design, what is the primary purpose of performing a 'frequency response analysis' for a chemical process?
Question 5
A chemical process is controlled by a PID controller. If the process consistently exhibits a sustained oscillation with increasing amplitude, what is the most likely cause related to PID tuning, and what corrective action should be taken?
