  • System for controlling a resonant linear compressor piston, method for controlling a resonant linear compressor piston, and resonant linear compressor
    Patent number: 9915260
    Abstract: A control method and a system for controlling the piston of a resonant linear compressor including at least one electronic control unit, the electronic control unit including at least one observing electronic circuit and at least one control circuit associated to each other. The observing electronic circuit is configured for: measuring at least one electric magnitude of the electric motor; estimating at least one set of electric parameters and at least one set of mechanical parameters of the resonant linear compressor; and estimating and providing at least one control parameter of the system for the control circuit based on the measured electric magnitude measured and on the estimated set of electric and mechanical parameters. The control circuit is configured for actuating the electric motor from the at least one control parameter.

  • SYSTEM FOR CONTROLLING A RESONANT LINEAR COMPRESSOR PISTON, METHOD FOR CONTROLLING A RESONANT LINEAR COMPRESSOR PISTON, AND RESONANT LINEAR COMPRESSOR
    Publication number: 20130189119
    Abstract: A system and a control method for the piston of a resonant linear compressor (100), especially designed for operating at their maximum efficiency, such a system being capable of actuating said compressor without the use of sensors for measuring mechanical magnitudes or variables. A method of controlling the piston of a resonant linear compressor, the steps of which enable one to estimate the velocity and the displacement of said piston, in order to control the compressor motor efficiently. A resonant linear compressor (100) provided with a control system as proposed.
