Title: Design of digital PI regulators from experimental frequency response of electrohydraulic steering system
Keywords: frequency response, digital PI-regulator, optimal tuning, electrohydraulic steering systems
Abstract: Paper presents the tuning of two digital PI regulators for electrohydraulic steering system designed for low velocity mobile machines. Regulators are based on experimentally measured frequency response of a steering system. This response is approximated with two rational transfer functions. They are basis for design of corresponding digital PI regulators with iterative optimization procedure in MATLAB / Simulink. Regulator parameters are programmed into a microcontroller for mobile applications and their performances are compared through natural experiment on the steering electrohydraulic drive system with digital control.
