  7. Abstract:
  8. A distributed model predictive control with two-layer structure for communication is presented in the present thesis for elimination of the propagation and amplificationphenomenon of the upstream transient errors in automated irrigation networks. This phenomenon results in the saturation of actuators in long automated irrigation channels and therefore it results in significant reduction in the quality of service of the irrigation network. Hence, the elimination of this phenomenon in long irrigation channels is necessary, in which a distributed model predictive control with two-layer structure for communication is presented in the presentthesis for elimination of this phenomenon. Feasibility, convergence and optimality of this method are mathematically proved. The satisfactory performance of this method in elimination of the mentioned phenomenon is illustrated and compared with the performance of a distributed model predictive control with single-layer structure for communication by applying these two methods to an automated irrigation channel and performing computer simulation. It is illustrated via computer simulation that the former method has a better performance by managing communication overhead
