<p>A turbine control device which compensates for non-linearity of the degree-of-opening/flow-rate characteristic of a regulating valve (14). The device has a turbine rotation speed detector (18), a calculator (20, 24) to determine a desired flow rate based on a predetermined rotation speed and the detected speed, a valve (14) for controlling the flow rate with a variable degree of opening, a flow rate detector (42), a memory unit (48) for memorizing combinations of the detected flow rate and respective degrees of opening of the valve, a converter (44, 46) for converting the desired flow rate into a valve opening command signal based on the memorized combinations of the flow rate and respective degrees of opening of the valve, and a servo controller (28) for the valve.</p> |
