In control theory, gain scheduling is an approach to
control of non-linear systems that uses a family of linear
controllers, each of which provides satisfactory control
for a different operating point of the system.

One or more observable variables, called the scheduling
variables, are used to determine what operating region the
system is currently in and to enable the appropriate linear
controller. For example in an aircraft flight control
system, the altitude and Mach number might be the
scheduling variables, with different linear controller
parameters available (and automatically plugged into the
controller) for various combinations of these two variables.

It is one of the simplest and most intuitive forms of
adaptive control.

I was working on calibrating turbidity transmitters endress+hauser at effluent polishing plant.We calibrated using NTU buffers.What happened is that when we immersed the sensor, everytime we raise and lower the sensor gradually, the reading will vary.my question is that is there any specifications on what is the required distance from the bottom of the container with buffer to the face of the sensor?Is it ok to install the sensor in a medium which has turbulence specially if bubbles are present?
