1. a high-temperature burning system fuel gas temperature control method and system thereof, it is characterised in thatCascade control method based on inverse dynamics model, specifically includes following steps:

  • S1 sets up the mathematical model of fuel oil supply system and air feed system, on this basisPropose suitable control method and realize the accurate control of fuel flow and air mass flow;

    S2 analyzes fuel oil combustion characteristics in high-temperature systems, uses the method for system identification to buildThe inversion model of vertical high-temperature burning system fuel gas temperature;

    It is straight that S3 sets up between high-temperature burning system fuel gas temperature inverse dynamics model and controllerConnect contact, obtain desired fuel flow and air flow value;

    S4 is according to changing the parameter of controller during the on-line identification fructufy of inversion model, thus realThe Self Adaptive Control of existing fuel gas temperature.
