A New Incremental Fuzzy PD+Fuzzy ID Fuzzy Controller

The PID fuzzy controller is fallen into one-dimension, two-dimension and three-dimension one in terms of structure, among which the two-dimension PID fuzzy controller is the most popular one. Based on these methods, a new two-dimension PID fuzzy controller, namely incremental fuzzy PD+ fuzzy ID is put forward. By comparing the illustration of the fuzzy PD and fuzzy ID, the conclusion that the two corresponding fuzzy control rules are similar is reached. The theoretical analysis shows that the PID fuzzy controller possesses the feature of non-linearity besides that of the traditional PID controller. The simulation research result shows that its control feature is better than that of the fuzzy PI and the conventional PID controller.
