Which of the following is not an objective of a control system?

• Stabilization

• Regulation

• Increasing unpredictability

• Robustness

What is the role of tracking in a control system?

• To ignore the reference trajectory.

• To follow the desired trajectory or behavior as closely as possible

• To minimize robustness.

• To increase system disturbances.

Which of the following is an advantage of the modern (time-domain, state-space) approach?

• It only works for linear systems.

• It is limited to systems with no initial conditions.

• It can handle nonlinear systems with phenomena like saturation and dead zones.

• It is only applicable for single-input, single-output systems

What is a possible disadvantage of feedback control?

• It cannot stabilize an unstable system.

• It may introduce instability even in a stable system.

• It cannot handle external disturbances.

• It requires a precise model of disturbances.

Which component is present in a feedback system but not typically in an open-loop control system?

• Controller

• Actuator

• Summing junction

• Sensor
