Embodiment Construction

[0051] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0052] The present invention provides a single neuron PID adjustment method for immune adjustment gain, including the following steps:

[0053] 1. The principle of immune adjustment gain single neuron PID regulator. This adjustment controller is divided into three parts, namely, neuron parameter self-adjustment, neuron PID gain immune adjustment and the controlled object loop. The neuron parameter self-adjustment mainly includes deviation Signal converter, neuron learning algorithm and neuron output, the specific structure graphics such as figure 1 As shown,

[0054] 2. Self-adjustment and combination of neuron parameters figure 1 Explain as follows

[0055] In the figure, r(k) is the k-th step to calculate the set value of the controlled object, y(k) is the k-th step to calculate the adjusted amount of the controlled object, e(k) is the control deviation signal, ...

Abstract

The invention discloses a single neuron PID regulating method achieving immunoregulation gain. According to the method, self-adaptive regulation of PID parameters can be achieved through the characteristic of combining self-adaptive neuron regulation with immunoregulation neuron gain, the workload of PID parameter tuning is greatly reduced, and the precision and the adaptability of parameter controlling are improved. Compared with a traditional tuning method, the method has the advantage that a unit can more safely, more economically and more stably run.

Description

[0001] Technical field: [0002] The invention relates to a PID parameter tuning method in the field of coordinated control of coal-fired units, in particular to a single neuron PID adjustment method of immune adjustment gain. [0003] Background technique: [0004] my country's electricity supply pattern dominated by coal-fired power stations will not be fundamentally changed for a long time in the future, and the coordinated and optimized control of coal-fired units has always been a key issue studied by many experts and scholars. At present, the coordinated optimization control method is still based on traditional PID adjustment control, and how to set PID adjustment parameters faster and better has always been an important issue. [0005] At present, there are many methods for PID tuning. The most traditional method is the Ziegler-Douglas tuning method. This method requires a large number of step disturbance experiments, and the tuning parameters are not optimal, but better. param...
