A method for controlling a steam turbine with a steam bleed for various operational tasks is provided. The operational tasks are each characterized by the type of the controlled variables used for controlling the steam turbine. A control structure is used for deriving actuating signals for actuating elements for valves. The actuating signals are derived from control signals of the regulators which are used. Only a single control structure is used for all the operational tasks. As a result, the configuration of the control is simplified, the control signals are decoupled, and a smooth changeover between the operational tasks is achieved. A device for controlling a steam turbine is also provided.

1. A method for controlling a steam turbine, the method which comprises:regulating a steam feed via a feed valve, and regulating a steam bleed via a bleed valve; supplying, with one of a first regulator and a second regulator, a first control signal and a second control signal to a regulating structure as a function of controlled variables fed to the one of the first regulator and the second regulator; linking, when there is a task-specific change between the first and second regulators, by using always a same regulating structure including a parameter set subdivided into subgroups, each subgroup having a first parameter and a second parameter, a result of a conversion of the first control signal with the second parameter and a result of a conversion of the second control signal with the first parameters to one another; determining a first actuating signal with a first one of the subgroups and determining a second actuating signal with a second one of the subgroups; and feeding the first actuating signal to the feed valve and feeding the second actuating signal to the bleed valve.
