Traditional pid dynamic structure

The longer the integration time, the smaller the integration control and the slower the adjustment rate. The operation method is as follows:

1. First of all, the parameter settings of the general PID controller in the simulation are shown in the figure.

2. Then the block diagram of adaptive fuzzy pid control system is given.

3. Then adopt integer separation strategy: 1. When the error is close to 0, the change of ki is positive.

4. Then the integral separation strategy is adopted: 2. The error is not near 0, and the change of ki is taken as 0.

5. Finally, the fuzzy rule table of Ki setting principle is as shown in the figure.
