Self-adaptive control method for full-load working condition of water turbine

The invention discloses a water turbine full-load working condition self-adaptive control method which comprises the following steps: step 1, adopting a generalized Smith predictor in a speed regulator to predict the working condition of a control object, establishing mathematical models of a water diversion system, a water turbine and a power generator, establishing a whole control object model, and establishing a model of the whole control object; establishing a mathematical model which does not contain a non-minimum phase term of which the steady-state gain is 1; and 2, aiming at the mathematical model of the non-minimum phase term without considering the steady-state gain of 1, adopting a shortest time controller to control, measuring the rotating speed of the unit, comparing the rotating speed with the output value of the whole control object model, correcting by utilizing a rotating speed given value, and simultaneously considering the difference adjustment requirement during the parallel operation of t
