碩士 === 國立勤益科技大學 === 電機工程系 === 104 === This thesis proposes a technique of sensorless induction motor control, which based on indirect rotor field-oriented control scheme to estimate rotary speed, stator resistance and rotor resistance simultaneously. In addition to establish decoupling estimator system by Popov's criterion and target influence about each other. Whatever, the topic of this thesis is based on full-order flux observer scheme to establish a speed estimator firstly and designs the speed estimator closed loop gain ranges of steady point around full range speed by Ruth-Hurwitz Criterion. Then, the particle swarm optimization (PSO) algorithm is used to estimate stator resistance and rotor resistance in time. Finally, it is simulated in MATLAB®/Simulink® platform to establish model to validate feasibility and it’s realized by a 32-bits DSP, RX62T type of RENESAS company.
