The invention relates to a control circuit () for a waste heat recovery system () for a heat engine (). The waste heat recovery system () comprises at least one evaporator () for converting waste heat from the exhaust gas () generated by the heat engine () into a working medium (), at least one expansion machine () which can be driven by the working medium (), at least one condenser () for condensing the working medium () expanded in the expansion machine () into the liquid state (), and at least one conveying device () for increasing the pressure of the condensed working medium () and conveying same into the evaporator (). The control circuit () influences at least one control variable which controls the energy transmission from the exhaust gas () to the working medium () and/or the energy transmission from the working medium () to the expansion machine (). The control circuit () is designed to regulate the specific enthalpy hand/or the temperature Tof the working medium () entering the expansion machine () to a target value h, T, wherein the target value h, Tdepends on the pressure pof the working medium () entering the expansion machine (). The invention also relates to a waste heat recovery system () for an internal combustion engine of a vehicle () in the form of a heat engine () comprising the control circuit () and to a corresponding computer program.

Control circuit for waste heat recovery systems

A method for controlling an automated or autonomous locomotive device, including automatically ascertaining a deviation from a predefined trajectory, the deviation requiring a return of the locomotive device to the predefined trajectory; automatically calculating a jerk as an input variable, as a function of the deviation from the predefined trajectory; automatically calculating an unconstrained correcting variable for the return to the predefined trajectory, as a function of a weighted sum that includes a weighted summand of the input variable and a weighted summand of the state for the return path; automatically calculating a constrained correcting variable regarding the jerk; the unconstrained correcting variable being manipulated via a cascade that includes multiple stages having one saturation function per stage; integrating the constrained correcting variable, to obtain a constrained return trajectory to the predefined trajectory; automatically steering the locomotive device to the predefined trajectory by way of the constrained return trajectory.
