This paper presents a simplified HF injection method for permanent magnet synchronous motor (PMSM) sensorless control. The discussed HF injection scheme utilizes motor magnetic saliency property which contains the information of the rotor position d
This paper describes a new control algorithm which can enhance the dynamics of a sensorless control system and gives a precise sensorless control performance. Instead of the conventional sinusoidal-type voltage injection, a square-wave-type voltage
An improved model-based wavefront sensorless adaptive optics algorithm is proposed for laser beam cleanup. Deformable mirror (DM) eigenmodes are used to replace traditional Lukosz modes in order to avoid DM fitting errors. The traditional method is b
