| Abstract |
This paper proposes a novel position/speed estimation method for a special type of armature sideexcited synchronous machine, namely heteropolar inductor machines, by taking advantage of themachines unique structural characteristics. The field winding characteristics of heteropolar inductormachines are analyzed firstly. Analytical approaches for developing q-axis position and rotor speedestimation algorithm are then discussed, based only on terminal voltage and current measurements.Finally the validity of theories is supported by practical experiments, and the performance ofestimations of position and speed under both steady state and transient conditions are shown byexperiments in a prototype machine. |
