Plasma equilibrium control methods, based on a multivariable control technique, are formulated in the hybrid poloidal coil system, where all of the many coils are designed for ohmic heating and controlling the plasma equilibria of a large tokamak. This formulation is divided into a program control method during the buildup phase and a feedback method for controlling the plasma current and the equilibrium during the steady-state phase. The former gives programming coil currents and voltages in order to reduce the required peak power by adjusting the magnetic field profile inside the plasma, keeping the plasma equilibrium fixed. The latter includes a proportional-integral (PI) control law in the conventional optimal control theory. Effective plasma equilibrium control by these methods was obtained in computer simulations for a fusion reactor with a major radius of 5.5 m.
