A method of monitoring the physical state of a hot-rolled sheet or hot-rolled strip while controlling a plate rolling train for the reversing working a hot-rolled sheet or hot-rolled strip is disclosed. For the reversing rolling of the hot-rolled sheet or hot-rolled strip a rolling stand is provided. At a starting point, an initial state of the hot-rolled sheet or hot-rolled strip in a model is determined, from which state at least one physical state variable is derived. Further, a cyclical updating of the state during the working of the hot-rolled sheet by using the model of the hot-rolled sheet or hot-rolled strip and the plate rolling train is provided, wherein monitoring of the path of the hot-rolled sheet or hot-rolled strip and operating parameters influencing and/or reproducing the state are taken into account.
