An adaptive velocity controller for a permanent-magnet synchronous motor without using shaft sensor is presented. Two line-to-line voltages and two stator currents are sensed to produce the flux position. The design part is concerned with the formulation of control algorithm for current-regulated pulsewidth modulated inverter and vector control strategy for speed loop. Under the vector control framework, self-tuning, model following, and model referencing adaptive control are applied to design for the speed-loop controllers. The implementational part integrates the control of current and speed loop using microprocessor-based controllers. Experimental case studies that correlate simulation and measurement results are provided. The experimental results validate the theoretical development. A new approach for designing advanced adaptive controller for a sensorless ac drive is provided.< >
