Abstract
Official abstract text for this publication.
Methods of providing a control band for a hysteresis controller are presented. A method can determine a control band analytically to avoid the time and costs associated with manual calibration of a hysteresis controller. By way of example, a method can include modeling a machine output, such as stator flux or machine torque, modeling the variation rate for the machine output, and providing a control band based on the variation rate modeling.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for determining a control band for a hysteresis controller, comprising: modeling an interior permanent magnet synchronous machine (IPMSM) output; modeling a variation rate for said machine output; and using said variation rate to provide said control band for said hysteresis controller. 2. The method of claim 1 , wherein said machine output comprises electromagnetic torque. 3. The method of claim 1 , w…
