Research On Algorithm Of The Steam Pressure System Controled By Fractional-order PI~λD~μ

In recent years, Fractional-Order Calculus mainly in signal processing,control, fluid mechanics,image processing, and soft matter are researched, but thereare no reports in the vapor pressure. Optimization of the steam system parameters notonly can improve theoperating efficiency of the vapor system, but also Bringconsiderable environmental and economic benefits for the enterprise. To promotefurther energy-saving enterprise steam system and provide a theoretical basis andtechnical support. The boiler is a nonlinear, multivariable, large time delay and thestrong interference the object of the complex regulation, the overshoot of traditionalPID control is too large, time of the system regulation too long, and the parametersare very sensitive to changes, System has very small changes will affect the systemcharacteristics, and make the whole control system instability, and the coupling effectof multiplevariables. In this paper, the fractional-orderPIλDμalgorithm can solvethe above problem.In order to able to effectively control the pressure of the steam system, the papermainly studies the application of the of Fractional-OrderPIλDμalgorithm in theboilersteam pressure. Because the Fractional-OrderPIλDμis relatively uniquemathematical background, this paper presents a mathematical theory model to studythe control algorithm of the fractional-orderPIλDμ. On the basis of mathematicalmodels, we Obtained and determined the Fractional-OrderPIλDμcontroller of thesteampressure system. Five parameters of the Fractional-OrderPIλDμaffect theperformance of the steam system being studied. Especially more than two parameterscompared to Integer-Order is studied. Matlab simulation observes the graphicaltransform of the frequency changes and the step response. Simulation results showthat the method is feasible. at the same time, Five parameters of the Fractional-OrderPIλDμsteam pressure control system carry on estimation parameter and parameter tuning.In practical applications, Fractional-OrderPIλDμalgorithm and DSP ofprocessing speed is very faster, they constitutes the high precision of the steampressure control system. Compiler environment of the system is DSP of the2000series integrated environment for the Code Composer Studio, Fractional-OrderPIλDμalgorithm procedure is the use of Matlab Link for CCS Developmen theTools, Matlab and CCS of the integrated development environment DSP areconnected. DSP executable code by Matlab simulation model generated directly.Therefore, From design of the Fractional-OrderPIλDμalgorithm to validation,from concept to code to achieve the whole chain, all the focus on validation of theprogram and development of the Fractional-OrderPIλDμalgorithm, the work ofthe Code development has become relatively simple.In the study system, we changed design of the conventional PID. The resultsshow that Fractional-orderPIλDμalgorithm is feasible. the algorithm improves thesystem steady-state performance in both robustness and dynamic performance. Butalso in the practical application of the boiler plant, steam turbine plant, thermalpower plants, chemical plants, has a certain theoretical and practical significance.
