Stabilizing Boundary Feedback Control in Networks of Multi-reach Canals
This paper presents the design of stabilizing boundary feedback control for an open-channel network composed by multi reaches based on a Lyapunov approach. The Lyapunov function and its time derivative are introduced. The sign property of the time derivative is equivalent to that of its second-order Taylor expansion. By use of the whole form of the second-order Taylor expansion without any simplifications, a class of boundary feedback controllers is presented to guarantee the local asymptotic closed-loop stability. The advantage of this approach is that only the water level depths at the gate boundaries are measured as the feedbacks.
