In order to control the plasma in the tokamak fusion reactor with a non-linearity and complexity, theoretical models of the major physical elements of the tokamak plasma are developed. By the integration of these models, the integrated simulation code that can handle consistently each physical model is produced. In this code, the heat and particle transport code of the core plasma is used as a platform for the integrated code, and the physics models of heating and current drive, MHD stability, diverter, high-energy particles effects are coupled to the platform code. Using the integrated code developed here, the integrated model is validated by the comparison with the experimental result. Complex phenomena of core plasma are elucidated, and guides toward the control of the core plasma are indicated. The integration code is contribute to the construction of a prototype version of the plasma simulator that complements the actual discharge of tokamak fusion reactor.

针对托卡马克聚变堆中等离子体的非线性和复杂性控制问题，建立了托卡马克等离子体主要物理量的理论模型。通过这些模型的集成，产生了能够一致地处理每个物理模型的集成仿真代码。在该程序中，堆芯等离子体的热和粒子输运程序作为集成程序的平台，并将加热和电流驱动、MHD稳定性、偏滤器、高能粒子效应的物理模型耦合到平台程序中。利用本文开发的集成程序，通过与实验结果的比较，验证了集成模型的有效性。阐明了堆芯等离子体的复杂现象，指出了控制堆芯等离子体的方向。该集成代码有助于构建等离子体模拟器的原型版本，以补充托卡马克聚变反应堆的实际放电。
