A control method and system for a resonant linear compressor applied for controlling the capacity of a cooling system. The method includes: a) reading a reference operation power (P) of the motor of the compressor; b) measuring an operation current (i); c) measuring an operation voltage of a control module of the compressor; d) calculating an input power (P) of the motor as a function of the operation current (i) and of the operation voltage; e) comparing the input power (P) with the reference operation power (P); f) if the reference operation power (P) is higher than the input power (P), then increase an operation voltage of the compressor (UC); g) if the reference operation power (P) is lower than the input power (P), then decrease the operation voltage of the compressor (UC).

Control method for a resonant linear compressor and an electronic control system for a resonant linear compressor applied to a cooling system

A linear compressor () applicable to a cooling system () includes a piston () driven by a linear motor (), the piston () having displacement range controlled by means of a controlled voltage (V), the controlled voltage (V) having a voltage frequency (&#x3c6;) applied to the linear motor () and adjusted by a processing unit (), the range of piston () displacement being dynamically controlled in function of a variable demand of the cooling system (), the linear compressor () having a resonance frequency, the processing unit () adjusting the range of piston () displacement, so that the linear compressor () will be dynamically kept on resonance throughout the variations in demand of the cooling system ().
