Abstract

An air conditioner temperature control apparatus comprising: a remotely controlled signal receiving unit for setting-up room temperature; a temperature detecting unit for detecting room temperature; and a control unit for carrying out fuzzy logic by inputting the detected room temperature and the temperature error between detected room temperature and set-up room temperature and for compensating the temperature error to linear-control an operation frequency of the compressor by inputting the compensated temperature error.

Claims

1. An air cnditioner temperature control apparatus comprising:

remotely controlled signal receiving means for setting-up room temperature;

temperature detecting means for detecting room temperature; and

control means for carrying out fuzzy logic by inputting the detected room temperature and the temperature error between detected room temperature and set-up room temperature and for compensating the temperature error to linear-control an operation frequency of the compressor by inputting the compensated temperature error.

2. The air conditioner temperature control apparatus, as defined in claim 1, wherein the control means comprises:

a whole fuzzy compensation unit for carrying out fuzzy logic with the input of the temperature error between set-up room temperature and the detected room temperature to compensate the temperature error; and

a PI control unit for linear-controlling with an input of a compensated temperature error, addition of a compensation term which is an output from the whole fuzzy compensation unit and temperature error.

3. The air conditioner temperature control apparatus, as defined in claim 1, wherein the whole fuzzy compensation unit comprises:

a fuzzy unit for inputting the room temperature set up with the remotely controlled signal receiving means and the temperature error to fuzzify same;

a fuzzy logic unit for performing a fuzzy logic by utilizing the set-up temperature and the temperature error fuzzyfied at the fuzzy unit according to a minimum--maximum fuzzy method; and

a non-fuzzy unit for calculating an area occupied by respective output values according to the minimum and maximu output values obtained by the fuzzy logic unit for determining a weight center of the areas and to add same to the temperature error to take same as the compensated temperature error.
