Abstract
The present invention relates to a system and method of controlling a linear compressor (), which is capable of fine-tuning the compressor when necessary, throughout the operating period of the compressor, so that said compressor operates at maximum capacity, wherein the piston () achieves a maximum displacement amplitude, closely approaching the cylinder head () without colliding with it. The system and the method according to the invention are also intended to control the operation of the linear compressor throughout its operating period, also seeking to maximize its performance and to reduce or optimize its power consumption. According to the present invention, the fine-tuning and control of the operation of the linear compressor are carried out by means of the combination of a technique for controlling a compressor without a sensor, and a technique for controlling the compressor with the aid of a sensor.
