Valve opening between 0 and 1. Nonlinear flow through valve. Three steps up on the reference. The response gets worse and worse. The third response is marginally stable and the valve saturates in the upper limit (fully open).. Blocking -. A block is a group of homogeneous experimental units. Maximize the variation among blocks in order to minimize the variation within blocks. Reasons for blocking. To remove block to block variation from the experimental error (increase precision).

STEADY-STATE ERROR. The difference between the output and the reference in the steady state was defined as the steady-state error.. In the real world, because of friction and other imperfections and the natural composition of the system, the steady state of the output response seldom agrees exactly with the reference. .

The purpose of feedback is to reduce system error. Introduction. All transmitted signals will contain some rate of error (>0%). Popular error control methods include:.
