Preview Questions Control Systems Engineer | Role Specific Skill

Question 1: How does the use of a process automation system improve the reliability of chemical manufacturing?

Which action should you take?

Choose only one option

By allowing more human intervention and manual adjustments

By minimizing the use of sensors and automation components

By reducing human error and ensuring consistent control over complex processes

By introducing more variability in the control parameters

Question 2: How do you incorporate safety instrumented systems (SIS) into the control system design for chemical processes?

Which action should you take?

Choose only one option

By using them only for controlling temperature

By using them only for monitoring and excluding them from automatic controls

By designing them as separate systems to ensure operator safety in case of failure

By integrating them with the primary control system to handle critical failure scenarios

Question 3: In a PID-controlled chemical mixing process, how do you ensure that the system maintains proper setpoint despite varying material properties?

Which action should you take?

Choose only one option

Increase the integral gain to account for changes in material properties

Adjust the setpoint based on manual observations

Use feedforward control in combination with the PID controller

Use a proportional-only controller

Question 4: In a PID-controlled level control system, what happens if the proportional gain (Kp) is set too low?

Which action should you take?

Choose only one option

The system becomes unstable with excessive oscillations

The system response becomes sluggish, and the process may not reach the setpoint

The system reaches the setpoint too quickly, leading to overshoot

The system performs as expected without any noticeable change

Question 5: What role does SCADA play in predictive maintenance in a petrochemical plant?

Which action should you take?

Choose only one option

SCADA only supports production control, not maintenance

SCADA systems do not contribute to maintenance processes

SCADA systems are used to manage human resources for maintenance

SCADA systems collect data that can be analyzed for patterns, helping predict equipment failures before they happen

Question 6: What is the primary challenge when designing control systems for highly dynamic chemical processes?

Which action should you take?

Choose only one option

Simplifying the sensors used in the system

Ensuring fast system response and stability despite disturbances

Minimizing the complexity of control loops

Reducing the size of the control panel
