Fuzzy control logic. Fuzzy control logic is a method of handling and processing information in the same way that a human being does. Thus allowing the management of inaccurate information and uncertainty through diffuse logic. The great advantage of this new methodology is use of expert knowledge in the automation of the tasks to be carried out.

2015-9-10  Thus the widespread thickener operation with poor standards, overflows with high fine particle contents and high variable underflows in many plants are understandable. In order to resolve these problems, a fuzzy logic controller with two basic control loops was suggested by Santos et al. (1995). One is to control underflow concentration by ...

A fuzzy logic controller is designed to simulate the FLES once it has been verified with the rule viewer using MATLAB Simulink. The FLC block in Simulink has two inputs (PE and RPE) and one output (flow rate). Figure 18 shows the finalized FLC with all the sources and sinks connected to it. Since the load distribution affects the total PC significantly, position (h) of the vehicle is used as a ...
