Questions & Step-by-Step Solutions

What is the time constant of a second-order system with a damping ratio of 0.5 and natural frequency of 2 rad/s?
  • Step 1: Identify the damping ratio and natural frequency from the question. The damping ratio is 0.5 and the natural frequency is 2 rad/s.
  • Step 2: Write down the formula for the time constant of a second-order system: time constant = 1 / (damping ratio * natural frequency).
  • Step 3: Substitute the values into the formula: time constant = 1 / (0.5 * 2).
  • Step 4: Calculate the product of the damping ratio and natural frequency: 0.5 * 2 = 1.
  • Step 5: Now, calculate the time constant: time constant = 1 / 1 = 1.
