碩士 === 國立宜蘭大學 === 電機工程學系碩士班 === 100 === This thesis proposes a DSP-Based induction motor simulation system, which uses the DSP chip and FPGA induction motor simulator to establish a low-cost and high safety induction motor simulation system which can replace the high-risk, bulky and expensive actual induction motor drive. The basic hardware architecture of the entire system includes an F2812 DSP development board which serves as the controller and an FPGA simulator proposed by the reference [1], which serves as the control device. And the building processes of the proposed simulation system can be divided into three stages. The first stage is the computer simulation stage. We use Matlab-Simulink® to simulate the control algorithm and confirm the feasibility of the overall architecture. Then, we simulate the induction motor constant V/f ratio control and rotor flux oriented control. The results of the computer simulation are used as references for debugging in the subsequent stages. The second stage is the emulation stage. In contrast to the computer simulation stage, the emulation stage will use the proposed simulation system to implement the constant V/f ratio open-loop control and rotor flux oriented control. This step can avoid equipment damage caused by controller program design error. Finally, the third stage is the actual validation stage. After confirming the correctness of control program, we connect the controller to the actual AC induction motor drive to implement the same control rule that is implemented in the emulation stage. Then we can prove the correctness of the proposed simulation system by showing the responses obtained in this stage, which are similar to the responses obtained in the emulation stage.
