Steady State Error Coefficients(Kp,Kv.Ka)/Effect of input signal on steady state Error
STEADY STATE ERROR CONSTANTS/ COEFFICIENTS
They are the measure of steady state errors
The system must be stable in order to find steady state error constants
Classification
1.Positional Error Coefficient(Kp) →Step signal :
When step input is given Positional error coefficient will control the error
2.Velocity Error Coefficient(Kv) →Ramp signal :
When ramp input is given Velocity error coefficient will control the error
3.Acceleration Error Coefficient(Ka) → Parabolic signal :
When parabolic input is given acceleration error coefficient will control the error
