FAQs on Steady State Error with unit step input for Type 0, 1 & 2 system in Control System Video Lecture - Control Systems - Electrical Engineering (EE)

1. What is steady-state error in control system?
Ans. Steady-state error in a control system refers to the error between the desired output and the actual output of the system after it has reached a stable state in response to a specific input.
2. How is steady-state error affected by the type of the system?
Ans. The type of the system (Type 0, Type 1, Type 2) determines the behavior of the steady-state error. Type 0 systems have a non-zero steady-state error for a unit step input, Type 1 systems have zero steady-state error, and Type 2 systems have zero steady-state error for ramp inputs.
3. How is steady-state error calculated for a unit step input in a Type 0 system?
Ans. The steady-state error for a unit step input in a Type 0 system can be calculated using the formula: ess = 1/(1 + Kp), where Kp is the steady-state gain of the system.
4. What are the factors that can contribute to steady-state error in a control system?
Ans. Some factors that can contribute to steady-state error in a control system include system parameters, controller design, disturbances, and modeling errors.
5. How can steady-state error be minimized in a control system?
Ans. Steady-state error can be minimized in a control system by tuning the controller parameters, improving the system dynamics, reducing disturbances, and using feedforward control strategies.
