By using the binary three-point interpolation method, the number of levels of E and EC in their domain tends to infinity. This not only satisfies the control rules formulated by the query table in Table 2-1, but also supplements infinite new and refined control rules between adjacent levels in the control rule table through linear interpolation, further enriching and improving the original control rules, and fundamentally eliminating quantization errors and adjustment dead zones, Overcoming steady-state errors and flutter phenomena caused by quantization errors, significantly improving system performance, especially steady-state performance.

2.2.2 Fuzzy Control Algorithm with Deadband
To avoid frequent control actions and eliminate oscillations caused by frequent actions, a control algorithm with dead zones is a good solution.
In the above equation, the dead zone e0 is an adjustable parameter, and its specific value can be determined experimentally based on the actual control object. If the e0 value is too small, the control action is too frequent and cannot achieve the goal of stabilizing the controlled object; If the e0 value is too large, the system will experience significant lag.
The system structure of the fuzzy controller with dead zone is shown in Figure 2-3, and this control system is actually a nonlinear system. When | e (k) | ≤ | e0 |, the output of the fuzzy controller is zero; When | e (k) |>| e0 |, the fuzzy controller has an appropriate output.
