Abstract

It is described a system (100) for controlling a gas turbine (105), comprising: a control system (101) for providing control signals (103) to a gas turbine (105); a tuning system (107) for providing tuning signals (109), a modelling system (111) for generating virtual measurement signals (113), the virtual measurement signals being based on the control signals (103) and the tuning signals (109); a sensor diagnostics system (115) for diagnosing at least one sensor measurement signal (117) and outputting control system reconfiguration signals (119) to the control system (101) and tuner system reconfiguration signals (121) to the tuning system (107), the tuning signals (109) being based at least on the tuner system reconfiguration signals (121), the control signals (103) being based on the at least one sensor measurement signal (117), the virtual measurement signals (113) and the control system reconfiguration signals (119).
