An airplane is provided. The airplane includes a fuel gauging and quantity estimation system with an improved estimation accuracy. The fuel gauging and quantity estimation system operates by detecting an environment of a tank comprising a liquid and selecting one or more liquid gauging algorithms based on the environment. The fuel gauging and quantity estimation system further operates by receiving sensor data characterizing the liquid of the tank and utilizing the sensor data and the one or more liquid gauging algorithms to determine a property of the liquid.

Fuel gauging system and improved methodology for fuel quantity estimation

A power converter system comprising a power source; a plurality of voltage source converters for driving respective loads; the plurality of voltage converters connected to the power source via a common DC-link, control means () for driving the voltage source converters by means of respective control signals modulated onto respective modulation carriers; and means for synchronizing the control means such that the respective modulation carriers are interleaved with a selected phase shift therebetween.

Motor drive system

Systems for exchanging information between a cargo handling system of an aircraft and a Power Drive Unit (PDU) are described herein. The systems include a power source provided within the aircraft and a first PDU provided within the aircraft. The power source is capable of providing DC power to the at least one PDU via an electrical power line. The power source further including a first Power Line Communication (PLC) node and the PDU further including a second Power Line Communication (PLC) node. The first PLC node being capable of communicating with the second PLC node via the electrical power line.

Communication system and method for an aircraft cargo/freight handling system

A system for modulating a current level of a power grid includes a perturbation module that injects a sinusoidal signal, at a cross-over frequency, to modulate a duty cycle to a power converter connected to the power grid; a current controller that monitors a reference current and a current at grid-side terminal of the power converter, the current controller further monitors a current of the power grid; and a parameter calculation module that calculates a plurality of gain values for the current controller based at least in part on a phase margin, a cross-over frequency, a current of an alternating current side of the power converter, and the duty cycle.
