Title: Implementation of embedded three-loop control algorithm for electrohydraulic power steering system
Keywords: control algorithm, electrohydraulic, embedded, steering, three-loop
Abstract: The paper presents the design, synthesis and implementation of a three-loop cascade control algorithm with a digital proportional integral regulator intended for installation in a modern electrohydraulic power steering systems for low speed vehicles. The developed control algorithm is embedded into a 32-bit microprocessor of a laboratory test rig. The structure of control system and the layout of the hydraulic system are shown. The cascade control algorithm consists of three regulators for output variables: proportional spool valve position, supplying flow rate and cylinder piston position. The parameters of PI regulator are tuned by model-based approach in Simulink environment and experimentally are refined. Evaluation with experiments have been carried out to present the performance of the electrohydraulic power steering system..
