Plasma control during tokamak operation is a key domain for magnetic confinement fusion research. Electron density profile, especially at the plasma edge, affects or reflects the plasma performances. Standardly, edge density profiles on the radial axis are computed with microwave reflectometry diagnostics to study the plasma profile post-discharge. Real-time (RT) measurements of reflectometry would be a promising tool to perform advanced control experiments and face the plasma control challenges. RT estimation of the edge density profiles has been computed with extraordinary mode reflectometry for the first time on WEST, and offers innovative sensors for plasma edge feedback control. The measurements provide a precise knowledge of the edge density profiles with the absolute radial position, in opposition to the RT ordinary mode reflectometry that provides relative radial profiles. Density at an absolute radial position has been used to perform edge density feedback control. Density at a relative position in the plasma has been used to perform density feedback control of a shifting plasma. Radial position of fixed densities at the edge are used to perform plasma position feedback control. These experiments enhance the novelty of the radial profile estimation for RT plasma control. The RT processing of reflectometry measurements is discussed in terms of variability and time delay, both influencing the control loop performances.
