In a hard disk drive (HDD), the zero crossing points (ZCPs) of back-EMF generated in the spindle motor armature windings are used as rotor position signal for realizing precision motor speed control. The error of ZCP is a major concern, especially for HDDs with ultrahigh data recording densities. In the paper, several causes that induce the ZCP error are analyzed, and these problems are induced during...
In this paper, a nonlinear PI controller is developed to control speed of PMSM, it can adjustment of controller parameters automatically in order to achieve the best control effect in control process. Simulation results show that it was faster than the traditional controller response and have a smaller overshoot.
The present paper describes a new flux-weakening (FW) algorithm for speed control of permanent magnet synchronous machine (PMSM) using a sliding mode observer (SMO) for rotor speed and position estimation. In flux weakening techniques needed to applications requiring constant torque and power operation, the produced torque is depended on the negative d-axis stator current applied to waken the magnetic...
Permanent magnet synchronous motors feature high power density, high torque to inertia ratio and high conversion efficiency. These characteristics made them advantageous to use in specific applications such as robotics and traction. However, one of the major drawbacks of these motors is the torque ripple, being especially harmful when a high performance position and speed control is required. Usually,...
This paper presents the use of a predictive technique to control the currents in a PMSM, driven by a voltage source inverter. This method allows for a high quality current control without using linear controllers and modulators, resulting in a conceptually simple solution. Simulation an experimental results confirm the good performance of the drive controlled by this method.
A novel energy-shaping controller design technique is used to the speed regulation of permanent magnet synchronous motor (PMSM). Using interconnection and damping assignment passivity-based control (IDA-PBC) methodology, assigning a desired port-controlled Hamiltonian (PCH) structure to the closed-loop PMSM system, speed controllers are designed when the load torque is known and unknown, respectively...
