Abstract: Disclosed are a method of estimating PV model parameters and a method and an apparatus for data-based PV fault detection and diagnosis using a PV model. The method comprises: substituting five parameters of a PV current, a diode saturation current, a diode ideality factor, a series resistance, and a parallel resistance into an output equation of a single diode model for PV modeling of a PV module; computing an MAEP in an output by comparing power-voltage (P-V) curve values of the PV module obtained from the single diode model, which is a PV simulation model, and P-V curve values of the PV module, which is an actual PV module, when the voltage is zero, the open-circuit voltage, or a specific data value increased as much as a preset intensity; and selecting parameters representing a minimum MAEP among a plurality of stored MAEPs as parameters of the PV simulation model.

Abstract: The present disclosure provides a method and an apparatus for quickly and accurately evaluating a trajectory of a projectile such as a satellite launching rocket or a missile by comparing the trajectory with a reference trajectory. The trajectory evaluation method includes: acquiring time series positioning data for a target and predetermined reference trajectory information; and mapping points representing the time series positioning data on a graph into corresponding points on a reference trajectory representing the predetermined reference trajectory information while relocating each mapped point onto a relocatable section taking into account a movable range dependent on a speed of the target, and determining a maximum value of distances moved by the points while the points are mapped and relocated as a similarity between the time series positioning data and the reference trajectory.
