Method for operating a flexible induction cooking hob comprising a plurality of inductors distributed next to each other to form a bi-dimensional array, said inductors being energizable by related inverters, said inductors being overlaid by a common cooking utensil or by different cooking utensils, and a control system (17, 18, 32) for driving said inverters, wherein the method comprises the following steps: - obtaining for each of said plurality of inductors a target energy or a target power to be delivered; - acquiring for each of said inductors in conjunction with its energizing inverter, a power vs. frequency curve; - defining a predetermined control (Tprog) period shorter than a thermal time constants of at least one of said cooking utensils, and longer than one halfperiod of the mains; - establishing for each of said inductors, in conjunction with its energizing inverter, an operating frequency range associated to said power vs. frequency curve; - establishing an activation sequence of said inverters in order that each single inductor is able to deliver said target energy, or said target power on average, over said control period (Tprog), in which each of said inductors can be energized in combination with at least a second inductor of said plurality of inductors, wherein, when said inductors are energized in combination, said combination of inductors being selected irrespectively of whether said each of said inductors and said at least second inductor are overlaid by the common cooking utensil or by different cooking utensils, and wherein said each of said inductors and said at least second inductor are provided with respective operating frequency ranges at least partially overlapping, wherein said activation sequence has duration corresponding to said control period (Tprog); and - activating said inverters according to said activation sequence; wherein said step of establishing an activation sequence of said inverters includes establishing to energize simultaneously said each inductor and the said at least second inductor, at a common operating frequency and during at least a first fraction of the control period (Tprog); and wherein the inductors and related inverters are divided in predetermined assemblies; characterized in that said target energy or target power to be delivered for each of said plurality of inductors is obtained through the step of estimating a residual energy or a residual power to be delivered by the said at least one of said inductors, and using in the activation sequence such residual energy or said residual power respectively as the target energy or as the target power to be delivered during at least a second fraction of the control period (Tprog) other than said first fraction. - obtaining for each of said plurality of inductors a target energy or a target power to be delivered;
