The causes of position estimation delays and their effects on the sensorless control of permanent magnet synchronous motor drives are investigated. The position of a permanent magnet synchronous machine is estimated via the injection of high frequency voltage signals. The delays under investigation are due to the digital implementation of the control(More)
In modern electrical drives, all regulators are implemented in discrete-time domain. The design of the current controller in the continuous time and its following discretization is a common and effective procedure as long as the ratio between the fundamental frequency and the sampling frequency remains sufficiently small. If this condition is violated, the(More)
