    Abstract: A method of providing ride-through capability in a chiller/refrigeration system employs a variable speed drive with an active converter stage, a DC link stage and an inverter stage for providing variable frequency and voltage to power at least one motor. An induction motor is coupled to the output of the inverter stage for driving a compressor in the chiller/refrigeration system. The ride-through method comprises operating the active converter to regulate the DC link voltage of the DC link stage to a predetermined voltage level until the current through the active converter equals a predetermined current limit, then transferring regulation of the DC link to the inverter upon reaching the current limit of the converter. The compressor is unloaded, and the power flow through the inverter is reversed to maintain the voltage level of the DC link stage. Pre-rotation vanes, slide valve, or check valve are used to unload the compressor.

    Abstract: A method is disclosed for controlling a synchronous motor by determining a rotor position of the synchronous motor based on estimating a flux linkage. The method includes applying a voltage of a stator winding of the motor to a transfer function. The transfer function includes an S-domain integration operation and an error correction variable. An output of the transfer function is processed to compensate for the error correction variable introduced in the transfer function. An estimated flux linkage is generated and an angle of the rotor position is computed based on the flux linkage. The computed rotor position is input to a controller for controlling a position or speed of the motor.
