Performance Monitoring of Control loops in Irrigation Channels using reference models
Abstract
In this paper a new approach for detection of oscillatory andsluggish controllers is developed. It is specifically aimed atcontrol systems where rejection of load disturbances is the maincontrol objective, and it is based on comparing the actual systemoutput with the output of a reference model. A number ofperformance measures are defined, and the user can also defineadditional tailor made performance measures. The developed methodhas been successfully applied to real data from an irrigationchannel. The method correctly detected the control loops whichneed retuning, and it provided useful information about severalaspects of the control performance such as speed of response,oscillations and interactions between control loops.
