SIDAC Architectures for Hydrostatic Transmissions

Given a transmission with a diesel engine, a variable displacement pump, a fixed or variable displacement motor and a load unit, the control architecture .hould handle the degrees of freedom of both engine and hydraulic units, starting from the directive. issued by a supervising level. A special clas8 of control. (SIDAC) calls for a aingla diredtive and hal additional automatic capabilities. Firstly, three variants that feature the dependence of the pump displacement on the engine speed are introduced. Then, two control architectures are analysed where the motor displacement is varlable.
