Abstract

Intelligent controllers are widely used in industries to control non-linear plants, for which mathematical models are difficult to obtain. Fuzzy logic controllers (FLCs) are often used for the same purpose as they operate on linguistic rules and estimation of uncertainty, which represents the core essence of non-linear systems. However, realization of FLCs on hardware platform is quite an arduous task in lieu of it high complexity and number of input parameters. In this paper, we have implemented an online FLC which can be operated remotely on a Virtex V LX110T FPGA hardware. The proposed FLC hardware is fed with fuzzy parameters over Ethernet on the fly. This system is tested extensively for water level control of a tank.
