  • Publication number: 20220383155
    Abstract: A plant water need computing system and method for forecasting water need to optimize irrigation efficiency while ensuring that a plant grows at optimal water availability. The plant water need computing system and method use a computational input and output balance model (CIOB model) implemented on a server to calculate irrigation need (IR) predictively. The CIOB model is implemented as a service through a representational state transfer application program interface (REST API). Registered clients get access to the API through a client application. Field identifier is passed by the client application to the CIOB model in an API request. The CIOB model sends an API response to the client application. The API response comprises irrigation need (IR). The CIOB model uses a computational module to calculate the IR and uses machine learning to optimize the plant water need.

  • Patent number: 11159113
    Abstract: In the fault-tolerant direct thrust-force control (FT-DTC) method, the generalized Clarke transform matrix and its inverse matrix are derived according to the fault-tolerant phase currents. The stator fluxes in ?-? plane are deduced based on these. Based on the requirement of circular stator flux trajectory, virtual stator fluxes are defined, and then compensatory voltages in the ?-? plane are obtained. Actual stator voltages in the ?-? plane are calculated by modulation function of voltage source inverter. Combining with the compensatory voltages, the actual stator voltages and the stator currents, the virtual stator fluxes and the thrust-force are estimated by the flux and thrust-force observers. The thrust-force reference, the stator flux amplitude reference, the observed thrust-force and virtual stator flux are applied to predict virtual stator voltage references.

  • Patent number: 10574164
    Abstract: The invention proposes a fault-tolerant field-oriented control method of five-phase interior permanent-magnet fault-tolerant linear motor (IPM-FTLM) with two nonadjacent short-circuit phase faults. Firstly, the extended Clark transformation matrix can be obtained according to the principle that magnetic motive force (MMF) keeps constant before and after the two-phase open-circuit faults, the constraint that the sum of healthy phase currents is zero and the adjacent two-phase current amplitude is equal. The back electric motive force (EMF) can be estimated by the transposed matrix. The nonlinear strong coupling system becomes the first-order inertia system when using the internal mode controller, the first-order inertia feed-forward voltage compensator and back-EMF observer, as the motor is with fault.

  • Patent number: 10505483
    Abstract: Disclosed are fault-tolerant permanent-magnet vernier cylindrical electric motors with an electromagnetic suspension and a fault-tolerant vector control method for a short circuit of two adjacent phases. The fault-tolerant permanent-magnet vernier cylindrical electric motor with an electromagnetic suspension and the fault-tolerant vector control method for a short circuit of two adjacent phases suppress motor thrust ripples caused by a fault of two adjacent phases of an electric motor. The dynamic performance and the steady-state performance thereof are consistent with those under a normal state, and the switching frequency of a voltage source inverter is constant.
