The error constant in a system always depends on steady state response of the system;

Steady state error constants of a system depend on the steady-state response of the system.


Steady-state error is the difference between the desired output and the actual output of a system after it has reached a stable operating condition. Steady-state error constants are mathematical values that determine the magnitude of the steady-state error for different types of inputs.


The steady-state response of a system is the output of the system when the input is a constant or periodic signal that has been applied for a long time. It represents the behavior of the system after all transients have decayed and the system has settled into a steady-state.


There are different types of steady-state error constants that are used to characterize the steady-state behavior of a system:

1. Position Error Constant (Kp): It represents the steady-state error when the input is a unit step function. The position error constant is a measure of the system's ability to track changes in the input.

2. Velocity Error Constant (Kv): It represents the steady-state error when the input is a ramp function. The velocity error constant is a measure of the system's ability to track changes in the rate of the input.

3. Acceleration Error Constant (Ka): It represents the steady-state error when the input is a parabolic function. The acceleration error constant is a measure of the system's ability to track changes in the acceleration of the input.


The steady-state error constants of a system depend on the steady-state response because they are calculated based on the steady-state error. The steady-state error is determined by comparing the desired output with the actual output of the system in the steady-state condition.

The steady-state response of a system is influenced by various factors such as system parameters, controller design, and disturbance rejection capabilities. These factors affect the system's ability to track changes in the input and determine the magnitude of the steady-state error.

Therefore, the steady-state error constants of a system depend on the steady-state response as they are calculated based on the steady-state error, which is a measure of the system's ability to accurately track changes in the input signal.
