This paper presents a linear dynamic model for the current and position of plasma in Damavand tokamak (DT) based on the RZIP methodology. Experimental data shots of DT are employed to validate the model and to show its accuracy. Since there are uncertainties in the model parameters, a robust decentralized control system is designed by considering the interaction between the input-output channels. Robust proportional and proportional-integral controllers are designed to obtain robust closed-loop stability and performance based on the Kharitonov theorem. The simulation results of the closed-loop system in two scenarios are presented to show the effectiveness of the introduced control system.
本论文基于RZIP方法,提出了达马万德托卡马克(DT)中等离子体电流与位置的线性动态模型。利用DT的实验数据射击对模型进行了验证,并展示了其准确性。鉴于模型参数存在不确定性,通过考虑输入-输出通道之间的相互作用,设计了一个鲁棒分散控制系统。基于哈里托诺夫定理,设计了鲁棒比例和比例-积分控制器,以实现闭环系统的鲁棒稳定性和性能。给出了两种场景下闭环系统的仿真结果,以展示所引入控制系统的有效性。
