Fuzzy Aeration Control for In-Bin Stored Grain

摘要

In this paper, we discuss mainly a new method for building the fuzzy controller for controlling aeration devices in the grain-storage system. This new fuzzy-control method is used for designing a special fuzzy-control strategy for the aeration management or in-bin drying stored grain. First, the method defines the fuzzy-control base variables which consist of the fuzzy-control membership function. Then, it constructs the fuzzy-control rule base which supports the fuzzy rule inference. Next, it implements the fuzzy rule inference, so that the rules in the rule base can determine the trace of action that the aeration devices must follow. Finally, it translates the result of the fuzzy inference from a linguistic concept to a crisp output value to drive the aeration devices. Thus, the aeration devices are automatically operated at suitable times to implement the scientific management for in-bin drying stored grain.
