Preview Questions Control Systems Engineer | Role Specific Skill

Question 1: How does a sliding mode control algorithm improve performance in a chemical plant with significant model uncertainty?

Which action should you take?

Choose only one option

By adjusting the control law based on the process state, improving robustness to uncertainties

By ignoring uncertainties and relying on a fixed control strategy

By using only feedback loops to reduce variability in control actions

By simplifying the model to eliminate uncertainty-related problems

Question 2: How do you handle a system where a PID control system produces a steady-state error in temperature control?

Which action should you take?

Choose only one option

Ignore the error and rely on manual control

Increase the integral time to eliminate the error over time

Use derivative control to correct steady-state error

Increase the proportional gain to reduce the error

Question 3: How do you ensure regulatory compliance in SCADA systems for chemical plants, especially with regard to process safety and environmental monitoring?

Which action should you take?

Choose only one option

Focus only on the plant's internal monitoring and ignore regulatory compliance

Ignore environmental compliance and focus on operational efficiency

Implement specific modules in SCADA for process safety and environmental compliance, ensure real-time monitoring, and include reporting features required by regulations

Ignore regulatory requirements to avoid complexity

Question 4: How do you ensure that the control system design accounts for both process optimization and safety in a chemical plant?

Which action should you take?

Choose only one option

Focus solely on optimization without considering safety

Ignore safety concerns and focus only on optimization

Design systems that include both process control strategies and safety instrumented systems (SIS) to handle hazardous situations and optimize operations

Maximize production without any regard to safety or regulatory standards

Question 5: What is the most critical factor when designing a process control system for a chemical distillation column?
