With the progress of the times and the rapid development of science and technology, more and more technological means begin to be gradually combined with production work. This way of combination has greatly increased the production efficiency of enterprises, but also saved the production cost of enterprises to a certain extent. It plays a very important role in promoting the development of enterprises. Under such a background, it is important for the boiler-steam industry.
It is more necessary to design fractional-order controllers for turbine systems. After consulting a lot of research data, thermostatic element the author summarizes and studies the relevant theories of fractional-order controllers design for boiler-turbine systems, and combines his own professional knowledge to study and analyze the design of fractional-order controllers for boiler-turbine systems, with a view to passing through this paper. This paper will be helpful for the design of fractional order controller of boiler-steam turbine system.
The society is progressing, the times are developing, and the technical means are constantly renovating.
In this situation, the innovation of production system has become the core of enterprise development. At present, the control problem of boiler-steam turbine system has become one of the hotspots of current research. For this phenomenon, more and more people launch integer-order and fractional-order mathematical models. The research shows that the fractional order mathematical model can be used to form control system for boiler-steam turbine system, which is more accurate and effective. For most of the dynamic systems in the real world, they are fractional order. In the boiler-turbine system, the fractional order mathematical model is used to describe the boiler-turbine system. Its accuracy is much higher than that of the integer order mathematical model. However, in the control research of fractional-order boiler-steam turbine control system, there are also some difficulties, which are reflected in the tedious parameter setting steps of the controller and the large amount of calculation by the owner. This problem leads to the application of this method in practical engineering is less than other methods. Most boiler-steam turbine systems should be integer-order in general.
The strategy of Cheng approximation, using the method of integer order model, is easy to control. However, such a method will reduce the accuracy of describing the system to a certain extent, unable to accurately reflect the dynamic characteristics of the system, and the constructed out-of-control controller can not enter the actual engineering operation process, and can not play a corresponding control effect.
Therefore, in the boiler-steam turbine system, the application of fractional-order controller is more important.
Implementing the correct operation can ensure the quality of the instrument. Designing the digitization of fractional order control in the use of the controller can effectively help the instrument operation and improve the quality of work. The concept of infinite dimension exists in the fractional order system. To use the concept of infinite dimension to help the content design of the instrument, it needs finite calculus programming.
In the process of processing, it is necessary to use finite calculus program to approximate the control function of the instrument. The method of designing controller in this paper mainly relies on time domain numerical method to operate fractional order, which is separated in PI lambda D? Control instrument function. The method designed in this paper is mainly to decompose the time domain numerical value by fractional stage small equation processing method, and realize the analysis and diffusion of time domain equation by PI_ lambda D_ control instrument function. The precondition of realizing fractional order is to ensure the errors considered in the calculation process to the actual operation, import the order em from the error value, and then output the numerical value of the controller in other ways. The output process guarantees the value um of the recording sequence. Finally, the fractional order can be effectively controlled and the digital function of the controller in PI λ D? Can be realized. This method can also be used in other research. It can ensure the simulation of research data and achieve specific experimental operations. If the set h is the actual step size and the range of the numerical value is suitable for the experimental range, the fractional stage formula can be obtained directly.
Through observation, it can be clearly found that the accuracy of the calculation of the data of period and time is very high. It shows that the numerical values and formulas can satisfy the design of other instruments in the process of research. Fractional differential has the function of memory. The closer the time is, the larger the factor of the influence point is, the smaller the factor of the influence point of the farther the time is. This ensures the influence of historical information on the present and future. It is more advantageous to improve the control effect of the system. In summary, there are many studies on the application of fractional-order controllers in boiler-steam turbine systems, but the research on the design of fractional-order controllers in boiler-steam turbine systems is relatively deficient. After integrating some related research literature, this paper begins to write. In the process of writing, it aims at fractional-order controllers in boiler-steam turbine systems.
The contents of controller design are introduced in detail. However, the author’s knowledge is limited.
The research on fractional order controller design of boiler-steam turbine system may not be perfect, but for the research on fractional order controller design of boiler-steam turbine system, it is still hoped that it can play a corresponding role.
