A method controls discharge temperature of a compressor of a vapor compression system. Using a mapping among discharge temperature, speed of the compressor, and outdoor air temperature, the method determines a desired discharge temperature for a new value of the speed of the compressor. The compressor is abruptly controlled to change the current speed of the compressor to the new value. A valve of the vapor compression system is smoothly controlled, such that the discharge temperature is transitioned to the desired discharge temperature according to a function of time representing a low pass filter with a time constant proportional to the thermal time constant of the compressor. |
