    Advanced control algorithm for stabilization rotational speed in hydrostatic transmission
    (Wydawnictwa AGH, 2006) Nawrocka, Agata; Kwaśniewski, Janusz
    This study focuses on the adaptive controller to control hydrostatic transmission. A hydrostatic transmission with a variable efficiency pump and a radial engine with constant working absorptivity was chosen. Pump efficiency was controlled using an electrohydraulic control system, comprising a hydraulic cylinder coupled with a pump rotor via a piston rod and a hydraulic servo-valve. As the object is nonlinear and time variant its control is very difjicult. For that reason the adaptive control strategy was chosen and a follow-up control algorithm was designed. This control strategy enables the fine tuning of the fuzzy logie controller's parameters. It can be done online, in each cycle time. Besides, this algorithm is implemented on a PLC controller. This paper outlines the structure of the controller and provides the results of laboratory tests.
