cvt control with the use of state space-based gain-scheduling

摘要

One of an engine driven machine provided with wheels, which has an improved engine overspeed- and combustion engines with overspeed protection, has a parallel transmission path, which a drive train with first and second gear inputs and a transmission output, and which likewise has a hydraulic variator or transducer, which has a variator, which drives the first transmission input, wherein the hydraulic variator a variable speed gear pump and has a variatormotor,the displacement of the variable speed gear pump by means of a variatoraktor, or is controlled variatorbetätiger. The machine further comprises a prime mover, which has a engine output the second transmission input drives and the drives variable speed gear pump, as well as a control unit for receiving one or more values, the one or more tensioning permissible speeds and / or rotational speeds of the engine, a value of the an actual rotational speed of the engine, and a value indicative of a position of the actuating variable speed gear carrier, the control unit is designed for adjusting the position of the actuating variable speed gear carrier based on " gain mapping " of the state period, in order to control the rotational speed of the engine within the one or more tensioning permissible rotational speeds of the engine to maintain.
