This study proposes a novel frame anti-vibration controller for position sensorless PMSM drive application. This controller is called specific component reduction controller (SCRC). SCRC can function without an accelerometer and can achieve speed variable control. This study mainly comprises the following phases. First, the position sensorless control method will be provided. Second, the frame ...

If productivity growth is taken to be exogenous, the rate at which jobs are created will determine growth in output. Assuming that employment is measured reasonably well, a policymaker armed with a measure of trend job growth will be a...
