Such a temperature is created by confining plasma via some poloidal coils. Control of voltages to be applied to the poloidal coils is an important control problem for proper operation of the overall system. This paper deals with the nonlinear robust control of plasma current, shape, and position in a Tokamak reactor. The paper briefly discusses the modeling issue of a Tokamak, and then, based on a nonlinear state-space model, presents three different versions of a robust controller for the process. All parameters of the system are assumed to be unknown for all three types of the controllers. Lyapunov-type arguments are used to prove the stability of the proposed control schemes. Advantages and disadvantages with each type of controllers are discussed in detail.en10.1088/1757-899X/261/1/012015info:eu-repo/semantics/openAccessConference Object261N/AN/A
