The paper summarises the design and the experimental results obtained with the new Plasma Shape and Current Control system (SC) of JET. This control system was brought in operation at the start of the 1994 plasma operation for the Pumped Divertor phase of the experiment. It has demonstrated the feasibility of plasma-wall gap control in a reactor relevant tokamak together with the possibility of using on-line a fast full plasma boundary measurement technique based on a large number of magnetic signals. Multiple Input Multiple Output (MIMO) design techniques have been used for the derivation of a suitable control structure. A multi variable decoupling controller capable of handling a combination of directly controlled circuit currents and plasma-wall gaps corresponding to the available number of degrees of freedom is the result of the work. During the pulse time evolution each circuit can be controlled in different ways. The control mode more appropriate for each phase of the pulse is chosen by the operator. The flexible design of the controller allows to include up to six plasma-wall distances to be controlled simultaneously. The control matrix used are calculated in real time according to the selected feedback array.
