Design of Fuzzy Logic Controller based on TMS320C6713 DSP

A Fuzzy Logic Controller (FLC) is designed with heuristic knowledge of the plant. There are several application based Fuzzy Logic Controllers in literature. However, application specific controllers lack reusability and are expensive, if not produced in bulk. This paper presents a general purpose and easily configurable fuzzy logic based controller which can work with 4 inputs and generates a control action based on the knowledge base. Expert operator knowledge can also be directly programmed into the knowledge base (also known as rule base) of the designed controller without ceasing the control operation. The ease of file handling and user interactivity of DSP processors is heavily exploited and TMS320C6713 DSP was chosen as the hardware platform. Further this paper also analyses the system performance with reference to the Fuzzy Logic Toolbox of Matlab.
