Apparatus and method for controlling linear compressor

Abstract

An apparatus and method for controlling a linear compressor are provided. In more particular, for solving the problem of limitation of compatibility in the present technology, the apparatus and method may identify a kind of motor of a linear compressor, based on an output which may be measured by applying a test signal to the linear compressor, and may control the linear compressor depending on the identified kind of motor. The apparatus and method may diagnose whether the linear compressor has broken down, and thus, the kind of motor may be autonomously identified without a separate device or a measurement operation, control suitable for a characteristic or characteristics of the motor may be accurately and efficiently controlled, and maintenance, repair, and inspection of the linear compressor may be simply and easily performed.

Description

technical field [0001] The present invention relates to a control device of a linear compressor and a control method of a linear compressor, more specifically to a control device of a linear compressor and a control method of a linear compressor that apply a test signal to identify a motor type, and control the linear compressor based on the identification result. Background technique [0002] In general, a compressor is a device that converts mechanical energy into compression energy of a compressible fluid, and is applied to refrigeration equipment, such as a part of a refrigerator or an air conditioner. [0003] Compressors can be divided into reciprocating compressors (Reciprocating Compressor), rotary compressors (Rotary Compressor), and scroll compressors (Scroll Compressor). A reciprocating compressor forms a compression space between a piston and a cylinder for sucking or discharging working gas, and the piston performs linear reciprocating motion inside the cylinder...

AI Technical Summary

Problems solved by technology

[0011] However, this method has gone through the inconvenient step of measuring the motor constant in advance and directly inputting it into the control program. If the control object of the control device changes due to maintenance, inspection, failure, etc., it is necessary to repeat this inconvenient process. steps to be able to control the compressor, so there are limitations

[0012] Or, each motor model has a specific control program built in to implement control, but because the specific control program is used, the types of motors that can be controlled are limited. If the control object changes, the control program needs to be changed one by one, so there is a limitation

In addition, in order to control various motors, multiple control programs need to be built in, but it is difficult to build multiple control programs, which greatly limits the compatibility of the control device
