   What limitation does integral control encounter without proper tuning?

   A Slow response time B Increased noise sensitivity C Risk of oscillations
8. 8

   In control systems, what is meant by "steady-state error"?

   A Transient deviation in response time B Initial system response lag C Difference between final output and set point
9. 9

   Which control action is responsible for stability against sudden changes in a system?

   A Integral action B Derivative action C Proportional action
