Problems solved by technology

With the development of technology, the application of dynamic pressure regulation is becoming more and more extensive. The existing automatic control technology only regulates the control variables based on the pressure error at the current moment. The execution lag of the mechanism is relatively large (especially the blower that regulates the gas concentration takes a long time to increase the wind power), and the hysteresis of this pressure regulation will be very serious, which will inevitably lead to the control overshoot in the control process of boiler pressure regulation And the problem of large steady-state error, so the overall control accuracy of the boiler is low, which cannot meet the needs of industrial production

Embodiment Construction

[0056] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0057] A predictive control method for boiler pressure regulation based on GRU-PID, such as figure 1 Shown is the framework diagram of the boiler pressure regulation predictive control method based on GRU-PID, the specific steps are as follows,

[0058] Step 1: Establish boiler pressure regulation control system, such as figure 2 Shown is a schematic diagram of the boiler pressure regulation control system, which is mainly composed of a blower with adjustable air volume, a fuel inlet pipe, a combustion chamber, a boiler chamber, a pressure feedback mechanism, and a steam output pipe. Among them, the pressure feedback mechanism generates the pressure value through the amplifier based on the electrical signal of the piezoelectric sensor, obtains the pressure value P of the boiler in real time, and uploads the pressure value to the host computer ...

Abstract

The invention relates to a boiler pressure regulation prediction control method based on GRU-PID. The method comprises the steps that step 1, a boiler pressure regulation control system is established; step 2, a trained GRU algorithm model is used for predicting pressures of the boiler in multiple time steps in the future; step 3, a correlation function based on the boiler pressure multi-time-stepcontrol error is calculated; and step 4, a boiler control system output based on the correlation function is calculated. According to the method, the multi-time-step control error correlation function is calculated based on the multi-time-step boiler pressure value predicted by the GRU algorithm, a problem of boiler control lag can be solved, and the boiler pressure control precision is remarkably improved.

Description

technical field [0001] The invention relates to the field of boiler pressure regulation control, in particular to a GRU-PID-based predictive control method for boiler pressure regulation. Background technique [0002] In the industrial field, boilers are widely used as a device for producing steam. The boiler converts liquid water into steam through the energy released by the combustion of fuels such as coal, oil or gas, and then the steam is directly supplied to the heat energy required in industrial production, or converted into mechanical energy and electrical energy through steam power machines and turbo generators. Among them, boiler pressure control is a crucial issue. The traditional method is manual regulation by experienced engineers. However, with the gradual increase in production requirements, the difficulty of boiler pressure control is gradually increasing, and the manual regulation method is inefficient. , the security is not high, so the method of automatic ...
