Adaptive Model Predictive Control of tokamak plasma unstable vertical position

摘要

The control system of a plasma unstable vertical position in the tokamak T-15 on the base of a Model Predictive Control (MPC) in discrete time for stationary and non-stationary plant models was synthesized and simulated. A comparison with a system containing a PID controller is presented. The predictive control showed better step response. The adaptive state observer was designed to estimate the unknown plant varying parameter on line which was used in the MPC algorithm to adapt it to the plant model.
