How would you handle a control loop that exhibits oscillations or instability?

To fix oscillations in a control loop, you can change the tuning parameters, mainly the proportional and derivative gains. Bringing down the gains can help keep the system’s response stable, and adding filters or smoothing algorithms might also work.

How can advanced control techniques such as model predictive control (MPC) improve process performance?

Model predictive control (MPC) and other advanced control methods use mathematical models of the process to guess how it will behave in the future and find the best way to control it. MPC looks at constraints, process dynamics, and goals to make the best choices. This leads to better process performance, less variation, higher efficiency, and a better ability to respond to disturbances.
