Abstract :
Aiming at the characteristics of multivariable, strong coupling, nonlinear and big delay existing in boiler-turbine coordinated system of ship power equipment, a compound control strategy based on support vector machine inverse identification was proposed, and it was applied to the simulation research of coordinated system. This method combined the support vector machine inverse control and fuzzy control, not only utilized the merits of support vector machine inverse control that designs easily and has good robustness, but also combined the advantages of fuzzy control that responses rapidly, has good anti-jamming capability and high reliability. It ensured the controller can be controlled from a rapid and steady state, even if the support vector machine was not training well. The simulation results showed that this compound control algorithm has a high performance in control quality, and puts up good performance on dynamic response speed, static stability, restrain big overshoot and robustness, etc.
