| Summary: | 碩士 === 國立台灣工業技術學院 === 電機工程技術研究所 === 85 === The purpose of this thesis is to investigate automatic
parameter identification for a standard squirrel-cage induction
motor. A new parameter measurement method is designed based on a
conventional induction motor parameters measurement method and
the field-oriented control theory.The feasibility of the
proposed measurement method is verified by both computer
simulation and hardware implementation. This thesis also
analyzes the effect of dead-time on drive performance. The
hardware compensation circuit is designed to overcome the dead-
time effect. Finally, the flux observer and speed estimator of
a sensorless rotor-flux-oriented-vector-controlled drive and the
signal processing of encoder feedback in a closed-loop vector-
controlled drive are also presented.In the hardware
implementation the single-chip microprocessor, the INTEL
80196MC, is used forcontrol software development. The hardware
circuits include both the sensorless vector control and the
(closed-loop) servo control hardware.The design of an
intelligent-power-module drive circuit is also presented. The
software package, MATLAB SIMULINK,is used for computer
simulation.The simulation and experimental results show good
performance under no-loadand loading conditions for both
sensorless and servo drives.
