2556การควบคุมแรงบิดโดยตรงสำหรับมอเตอร์ไฟฟ้าเหนี่ยวนำแบบเชิงเส้นThis thesis presents a construction of a three phase linear induction motor together with its drive control. The drive control of such motor is analyzed and then also built. The direct torque control in this thesis generate a voltage and reference frequency by using a motor torque and its magnetic flux error in order to control such linear motor. However the space vector modulation method are utilized in this work instead of using a stator flux and look-up table technique. A 1kW, 16 pole of three phase single-sided linear induction motor is constructed and built in this work. The motor drive is also built within a 10 kHz switching frequency. However the controller is composed of by using a TMS320F240 DSP board in order to generate a control signal for a inverter circuit, and using a DSPACE 1104 real time interfacing card in order to implement for a direct torque control method. Simulations results of the three phase linear induction motor was done by using MATLAB/SIMULINK and experimental results of such linear induction motor was also analyzed in this work. It shows that the proposed system provides a fast response of torque control comparing with a traditional V/F control. In practice, a transition time of motor torque is about 50 ms, while such controller of the linear induction motor has a command torque at 5 Nm.; อรรนนท์ บัวศรี
