Microstepping with Nonlinear Torque Modulation for Permanent Magnet Stepper Motors

  title={Microstepping with Nonlinear Torque Modulation for Permanent Magnet Stepper Motors},
  author={Vijayalakshmi and Nagesh Muniyappa and Nithin Awasthi},
A new approach to position control based on microstepping with nonlinear torque modulation for permanent magnet stepper motors is studied. The proposed method comprises nonlinear torque modulation, a commutation scheme, and a nonlinear current tracking controller. To improve the position tracking performance of conventional microstepping, nonlinear torque modulation is incorporated. Commutation schemes implementing fieldoriented control (FOC) are developed to construct the desired current… CONTINUE READING
