Using dynamic input allocation for elongation control at FTU

This document is a poster. In this work we exploit the dynamic allocation scheme for input redundant control systems to achieve elongation control on FTU. The scheme first serves as a means for regulating the current in the F coils. Then, due to the quasi-static relation between the plasma elongation and the F coil current, elongation control is achieved by suitably generalizing the allocation scheme. Both simulation and experimental results are reported. It is shown that the allocator can successfully assign a prescribed plasma elongation
