In this thesis, we use the least square approximation method to obtain the unkown system parameters of the equivalent linear motor dynamics. For sensorless controller design, we first use a state observer with armature voltage and current as inputs to obtain the rotor speed. We then use a 120-degree six-step square wave to control the insulated gate bipolar transistor (IGBT), instead of using an incremental encoder to obtain the rotor data for the speed sensing. Finally, we select the variable structure control to achieve constant speed control. Wu-Chung Su 蘇武昌 2019 學位論文 ; thesis 61 zh-TW |
