Optimizing indicator choosing for canal control system and simulation study

One key problem for canal system control is how to select appropriate performance indicators and how to tune the controller with these indicators. A canal system is a multi-input and multi-output (MIMO) system. The judging control performance can be extremely complicated. In this paper, frequently used canal system performance indicators are evaluated. Then these indicators are used individually to tune the control parameters for a simple proportional-integral (PI) controller on a test canal. Then we evaluated these controllers on this test canal through simulation. Based on these results, we develop a general performance indicator (I_G) that is a combination of the individual indicators. For this test case, it is shown that this indicator represents a good compromise. It is hoped that this approach can be used to develop a more robust method for determining criteria for controller tuning.
