LPV non-integer order model and control of an irrigation canal using gain scheduling technique

Abstract

In this paper, a novel method for controlling main irrigation canals with variable dynamic parameters is proposed. A non-integer order based gain-scheduling controller for canal systems is presented. This controller takes into account the variations of parameters in each operating point by using a linear parameter variable (LPV) non-integer order model obtained by fractional LPV identification. This non-integer controller has been designed in accordance with the control input bound and assure closed loop poles placement desired in all the working operation canal range. This approach is validated in a pilot canal plant. Control results guarantee the desired performance and stability for slow parameters variation in the whole operation canal range.
