Dynamic Response of Automatic Water‐Level Controller. Part II: Application
Publication: Journal of Irrigation and Drainage Engineering
Volume 116, Issue 6
Abstract
Constant water‐level controllers of various kinds are used within many irrigation canal distribution systems. In a companion paper, simple transfer‐function equations were developed for one style of automatic water‐level controller, the dual acting controlled leak system. Such information can be used to study the dynamic response of proposed designs. In this paper, these transfer‐function equations are used to evaluate the stability and dynamic response of the system. It is shown that these systems are always stable. Response times and control decrement are well modeled.
