针对托卡马克聚变堆等离子体控制的非线性和复杂性，建立了托卡马克等离子体主要物理要素的理论模型。通过这些模型的集成，产生了能够一致地处理各个物理模型的集成仿真代码。该程序以堆芯等离子体的热量和粒子输运程序为平台，耦合了加热和电流驱动、MHD稳定性、分流器、高能粒子效应等物理模型。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，并指出了堆芯等离子体控制的指导。该集成程序有助于建立等离子体模拟器的原型版本，以补充托卡马克聚变堆的实际放电。

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.
