Design of non-static controllers for plasma stabilization

This paper examines the problem of control synthesis which takes into account constraints of current in the coils of poloidal system. The necessary condition for control synthesis consists of astaticism providing on controllable states, because reaching of constraints of current may be treated as new constant disturbance in mathematical model. According to this demand different ways of astaticism providing are examined. Some theorems are proved, giving basis for these methods. New structure of generalized astaticism providing controller is proposed. It uses observer of special type. It is shown that unlike traditional method, which uses integrals of controlled states, proposed methods do not worse the plasma stabilization performance objectives.
