Mathematics and Computers in SimulationWe present an approach for the optimization of irrigation in a Richards' equation framework. We introduce a proper cost functional, aimed at minimizing the amount of water provided by irrigation, at the same time maximizing the root water uptake, which is modeled by a sink term in the continuity equation.

Optimizing semilinear representations for State-dependent Riccati Equation-based feedback control
IFAC-PapersOnLine, 2022 An optimized variant of the State Dependent Riccati Equations (SDREs) approach for nonlinear optimal feedback stabilization is presented. The proposed method is based on the construction of equivalent semilinear representations associated to the dynamics and their affine combination. The optimal combination is chosen to minimize the discrepancy between

Nonlinear state-dependent Riccati equation control of a quadrotor UAV [PDF]
2006 IEEE Conference on Computer Aided Control System Design, 2006 IEEE International Conference on Control Applications, 2006 IEEE International Symposium on Intelligent Control, 2006 Small quadrotor UAVs represent a very interesting class of small flying robots because of their ability to fly in- and outdoor. Therefore, these vehicles have an enormous potential for near-area surveillance and exploration. However, especially indoor flight is a difficult task for vehicle control which has to stabilize the desired velocity vector and ...
