What is time constant in second order system?

The second order process time constant is the speed that the output response reaches a new steady state condition. An overdamped second order system may be the combination of first two order systems. The time constant of undamped system is the greatest followed by the time constant of overdamped system, underdamped system and lastly critically damped system.

How to Calculate Time constant?

Time constant calculator uses Time constant=1/((Damping ratio-sqrt((Damping ratio)^2-1))*Natural frequency) to calculate the Time constant, Time constant of the response represents the elapsed time required for the system response to decay to zero if the system had continued to decay at the initial rate. Time constant and is denoted by T symbol.

How to calculate Time constant using this online calculator? To use this online calculator for Time constant, enter Damping ratio (ζ) and Natural frequency n) and hit the calculate button. Here is how the Time constant calculation can be explained with given input values -> NaN = 1/((0.1-sqrt((0.1)^2-1))*10).

FAQ

What is Time constant?
Time constant of the response represents the elapsed time required for the system response to decay to zero if the system had continued to decay at the initial rate and is represented as T=1/((ζ-sqrt((ζ)^2-1))*ωn) or Time constant=1/((Damping ratio-sqrt((Damping ratio)^2-1))*Natural frequency). Damping ratio is a dimensionless measure describing how oscillations in a system decay after a disturbance and Natural frequency is the frequency at which a system tends to oscillate in the absence of any driving or damping force.
How to calculate Time constant?
Time constant of the response represents the elapsed time required for the system response to decay to zero if the system had continued to decay at the initial rate is calculated using Time constant=1/((Damping ratio-sqrt((Damping ratio)^2-1))*Natural frequency). To calculate Time constant, you need Damping ratio (ζ) and Natural frequency n). With our tool, you need to enter the respective value for Damping ratio and Natural frequency and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
How many ways are there to calculate Time constant?
In this formula, Time constant uses Damping ratio and Natural frequency. We can use 4 other way(s) to calculate the same, which is/are as follows -
  • Time constant=Resistance*Capacitance
  • Time constant=Resistance*Capacitance
  • Time constant=Inductance/Resistance
  • Time constant=1/(2*frequency*pi*Capacitance)
