The paper deals with the identification of plasma equilibrium reconstruction in D-shaped tokamaks on base external magnetic measurements. methods such are directed to increase their speed response when discharges relatively short, like spherical Globus-M2 tokamak (Ioffe Inst., St. Petersburg, Russia). new approach is first apply data off-line algorithm based Picard iterations, and obtain gaps between boundary wall, second gap values, producing shape models operating real time. inputs for...

On 22 January 2024, at the age of 78, Yuri Vladimirovich Mitrishkin (Figure 1), an outstanding scientist and remarkable educator with half a century experience, passed away unexpectedly [...]

To design plasma magnetic control systems in modern tokamaks one needs models of the plasma. These are linear parameter varying (LPV) because relatively small variations outputs feedback loops around scenarios and may be obtained by first-principle equations, identification approach or their combinations. The challenge obtaining tokamak becomes more complicated existence position poloidal field with diagnostics actuators which needed as inner cascades for current shape particular on...

This paper suggests and develops a new methodology of estimation for multivariable reachability region plasma separatrix shape on the divertor phase discharge in D-shaped tokamaks. The is applied to spherical Globus-M/M2 tokamak, including controllability vertical unstable position basis experimental data. An assessment important design tokamak poloidal field coils synthesis magnetic control system. When designing it necessary avoid small vertically plasma, because such cases occur practice...

Artificial neural networks with different structures are used for identification of complex dynamic plant distributed parameters. The is a high-temperature plasma in the spherical Globus-M2 tokamak. Experimental data from it were processed by reconstruction code based on Picard iterations, namely, Flux-Current Distribution Identification (FCDI) code. This represents smart technology employed to obtain parameters minimizing difference between measured and reconstructed signals. An artificial...

Two-cascade plasma shape control system with decoupling was designed for a linear model of vertically elongated tokamak Globus-M2. The inner multivariable cascade controls currents in poloidal field coils, outer shape. In both cascades matrix is used. idea reversing relationship between inputs and outputs the steady-state regime. PID-controllers were tuned by QFT approach (Quantitative Feedback Theory). obtained non-linear models current invertors as actuators position simulated...
