Abstract
A block diagram of a typical position control system is given in Fig. 27.1, and an equivalent normalized system block diagram in Fig. 27.2. The free integrator inside the loop eliminates any residual positional error, which leaves three causes giving rise to steady-state errors, i.e. actuator velocity, actuator loading and valve hysteresis.
