The Fuzzy Microcontroller
edeX includes a fuzzy microcontroller (the XMCU) with a resident fuzzy controller algorithm.
Creating a fuzzy controller for a particular system involves customizing the XMCU for that application. All the designer needs to do is tune the knowledge-base (the controller parameters) and download it to the chip. edeX’s user-friendly tools are used to automatically tune the knowledge-base and to test the fuzzy controller performance directly on the application. edeX generates default fuzzy rules and membership functions, or the user can enter their own initial fuzzy rules and membership functions.
Minimal or No Knowledge of Fuzzy Logic is Required
In the automatic tuning mode, the user tunes the fuzzy controller by working with the process model, employing the fuzzy design software to automatically optimize the FLC parameters. The tuned KB is then downloaded to the chip for online testing.
At present, Xiera’s fuzzy technology resides on a dedicated STM32F051K microcontroller, which is driven by the host application microcontroller through a serial channel. For high-volume applications where low cost is important, or for high-performance designs, it may be desirable to have the fuzzy logic algorithm integrated with the rest of the application code on a single microcontroller.
In these cases, special consideration is required, please contact Xiera for details
