Abstract
A method of adjusting a process output in a material handling process. The velocity analog value of the material is determined and an instantaneous integral gain is then determined according to the velocity analog value. The output of a controller is then adjusted according to the instantaneous integral gain.
Claims3
A method of adjusting an output in a process for handling a material having a velocity analog value, and a process output value the method comprising steps of:
- a) determining the instantaneous integral gain according to the velocity analog value,
- b) determining a lower limit velocity analog value;
- c) determining a lower limit instantaneous integral gain for the lower limit velocity analog value;
- and
- d) setting the value of the instantaneous integral gain equal to the lower limit instantaneous integral stain if the velocity analog value is less than or equal to the lower limit velocity analog value.
- e) adjusting the process output value according to the instantaneous integral gain value.
