In order to improve the pressure stability and protection ability of the main gas pipeline of small gas kiln,the pressure stability control method of the main gas pipeline of small gas kiln based on expert system compensation control is proposed.The analytical model of pressure parameters of gas main pipeline of small-sized gas kiln is constructed,and the steady-state fitting of pressure output of gas main pipeline of small-sized gas kiln is carried out by using low reynolds number turbulence model.Combined with the joint characteristic analysis method of temperature and pressure parameters,the pressure fitting control model of gas main pipeline of small-sized gas kiln is constructed,and the pressure stability parameters of gas main pipeline of small-sized gas kiln are adjusted by the minimum yield strength analysis method.The multi-dimensional parameter feedback control method of pressure,temperature,pressure and yield response force is adopted to construct an expert system for pressure stability control of main gas pipeline of small gas kiln.Under the guidance of expert system rules,the pressure stability control and optimal feedback compensation of main gas pipeline of small gas kiln are realized.Simulation results show that this method has good stability and robustness in controlling the pressure stability of the main gas pipeline of small gas kiln.
