摘要： The present invention relates to a system and a method for controlling a motor. A rotation/fixed coordinates converter converts a reference magnetic flux voltage and a reference torque voltage of a rotation coordinates system into data of a fixed coordinates system, and outputs the data to the three-phase voltage generator. A fixed/rotation coordinates converter converts a three-phase current applied from the inverter to the motor into a two-phase current. An estimation unit estimates a rotation angle and rotor speed of the motor upon receiving currents applied to the fixed/rotation coordinates converter. A control block receives the estimated rotation angle and the estimated speed from the estimation unit, and outputs the reference magnetic flux voltage and the reference torque voltage of the motor to the rotation/fixed coordinates converter to compensate an error caused by loads generated when driving the motor. Thus, the control system greatly reduces noise and vibrations of a compressor without being affected by loads generated by compression/expansion strokes of the compressor at a startup time of the motor, and prevents a performance of the compressor from being deteriorated.

摘要： Provided is a high voltage wideband pulse attenuator having an attenuation value self-correction function. The high voltage wideband pulse attenuator includes an input unit for receiving a pulse signal, a T-shaped attenuator circuit for attenuating the pulse signal, an output unit for outputting the pulse signal attenuated by the attenuator circuit, and a capacitive divider circuit for dividing a voltage of the pulse signal input through the input unit or the pulse signal attenuated by the attenuator circuit. Using the capacitive divider circuit, the high voltage wideband pulse attenuator can easily measure an error of an attenuation value caused by a change in the resistance of T-shaped array resistor units in a process of attenuating an input pulse signal of tens of kV or more. In particular, the pulse attenuator can measure its performance by itself without test assisting devices, and check a state of an attenuated pulse in real-time.

摘要： Disclosed are a flux observer and a sensorless control system of a synchronous reluctance motor. The flux observer includes an estimated flux output unit, a measured flux output unit, and a fixed/rotational coordinate converter. The flux observer estimates a flux of a synchronous reluctance motor by removing higher harmonic components of a current in a rotational coordinate system which flows into the motor. The measured flux output unit measures a flux in a fixed coordinate system by combining a voltage in the fixed coordinate system, which is applied to the motor, and a current in the fixed coordinate system, from which higher harmonic components are removed, with the estimated flux outputted from the estimated flux output unit. The fixed/rotational coordinate converter converts the measured flux outputted from the measured flux output unit to a measured flux in the rotational coordinate system.
