i], H(t), and [delta](x) are the components of the point force source, Heaviside step function
, and Dirac delta function, respectively.
By definition, relaxation is the response to a theoretical step function
in the strain imposed on the specimen.
i] for all i, the TFC engagement corresponding with 1DOF system control configuration and if ([beta] = 0 for all i and setpoint and disturbance are a step functions
, it corresponding with 2DOF system control configuration.
As noticed by authors, the fact that the step function
method uses simple operation expressions, it's obvious that the numerical applications are being solved fast with a minimum number of computational cycles.
gives responses of the position control loop transfer function of 6-th and 2-nd order on step function
