In this note we comment on an error present in the recent and extensive literature on exact controllability of abstract control differential problems. Our observations are valid for first order, second order, integro-differential ...

A new concept of fertilizer machine is under development and shows as differential individually fertilizer application, that is sources of N, P and K are applied separately for the purpose of improving the distribution ...

Robust backstepping control of non-linear systems with derivation orders (commensurate or non-commensurate) lying at interval (0, 2) is proposed in this study. The stability and robustness properties are proved using a ...

In distributed processing systems it is often necessary to coordinate the allocation of shared resources that should be assigned to processes in the modality of mutual exclusion; in such cases, the order in which the shared ...

The mechanical harvesting efficiency of agricultural crops affects operational quality and production costs while being dependent on plot shape, operation planning, and management. Therefore, this study evaluated the ...

This paper introduces a strategy to control a three phase voltage source inverter used in distributed generation in microgrids scenario. In this context, the inverter should operate in grid connected and islanded modes. ...

This paper presents a new methodology for the operation and control of a single-phase current-source (CS) Boost Inverter, considering that the conventional current-source inverter (CSI) has a right-half-plane (RHP) zero ...
