A Fuzzy Logic Approach for an Electrical Power Steering System 2005-01-1276
This paper investigates the process of building a fuzzy logic Electrical Power Steering (EPS) system. The EPS prototype described in the paper dynamically generates a variable torque assist depending on the combination of the momentary values of vehicle weight, velocity, lateral acceleration, battery voltage, and tyre pressure. The process of modeling and simulating the prototype in MATLAB/Simulink is described. The paper presents the research experience indicating that the use of fuzzy logic to design an Electrical Power Steering system delivers a rapid development time and a direct and natural way to capture the required functionality.
