Abstract
The paper investigates the design of H2 and H∞ controllers for a permanent-magnet synchronous motor drive system without using shaft-position sensor, and presents the field-weakening control algorithm of the drive system. Robust PI, H2 and H∞ control techniques are applied to design servo controllers. A fully digital control system under the vector control framework is constructed for experimentally verifying controller performance. The theoretical development is validated by experimental work. The paper provides a new approach for designing sensorless AC drives using currently available high performance microprocessors.Keywords
