Abstract

This chapter addresses distributed LQG control of multipurpose open water channels, used both for water delivery and vehicle transportation. The use of a local control agent structure of the so called local upstream control type ensures that the water level is kept close to a desired level, even in the presence of disturbances caused by water turnout at side offtakes, so as to ensure navigability. Local control agents are modified LQG controllers coupled with a nonlinear compensation of the nonlinearities induced by the gates nonlinear models. The coordination among local controllers is achieved through an algorithm based on game theory that drives the local decisions to a Nash equilibrium. Experimental results in a large scale pilot canal are included to demonstrate the control concepts proposed.
