Title:
METHOD FOR CONTROLLING ROTATIONAL SPEED FLUCTUATION OF SINGLE ROTOR COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2020/119208
Kind Code:
A1
Abstract:
Disclosed is a method for controlling the rotational speed fluctuation of a single rotor compressor, comprising the process of controlling the compressor according to the real-time angle speed and the torque. The process of controlling the compressor according to the real-time angle speed comprises the following steps: performing filtering processing to the axis error to obtain an angle speed compensation dosage; compensating the angle speed compensation dosage to the output angle speed of the phase-locked loop regulator to obtain a compensated angle speed output quantity; correcting the real-time angle speed according to the compensated angle speed output quantity, and controlling the compressor according to the corrected real-time angle speed. The process of controlling the compressor according to the torque comprises the following steps: calculating the difference between a target angle speed fluctuating quantity and a feedback angle speed to obtain a first angle speed difference (21); performing filtering processing to the first angle speed difference to obtain a filter angle speed (22); inputting the filter angle speed into a speed ring regulator to obtain an output torque (23), and controlling the compressor according to the output torque (24). The method is able to improve the validity of inhibiting the rotational speed fluctuation of the compressor.
