Process Gain

  Process Gain The system function is the symbolic representation of how a process component changes its output in response to a change in its input. For example, if the system function is only a gain, only a constant (Kc, G, or some other symbol) would appear inside the block. The process gain is the ratio between the change in the output (dc) and the change in the input that caused it (dm). If the input (m) to the block is a sinusoidal, the output (c) will also be a sinusoidal.  The process gain can be the product of a steady-state gain (Kp) and a dynamic gain (gp) component. If the gain varies with the period of the input (exciting) sinusoidal, it iscalled dynamic gain (gp), while if it is unaffected by this period it is called steady-state gain (Kp). Therefore, if the process gain can be separated into steady-state and dynamic components, the system function can be given inside the block as (Kp)(gp).  The dynamic gain (gp) appears as a vector having a scalar component Gp and a phas
