摘要： To allow for apparatus tolerances, aging of equipment, and changes in operation, for example due to changes in temperature, in a closed-loop servo system in which an operator-controlled fuel supply control element (1) provides, via a coupled command control transducer (2), a signal to control a positioning motor (8) which moves a fuel supply control element (9, 29) in accordance with deflection of the operator control panel, a logic and calculating element, in form of a microprocessor (3) is provided, included in the control loop. When the fuel control element, for example a throttle in the induction pipe of an Otto-type internal combustion engine (ICE) or a fuel injection controller of a Diesel engine reaches a predetermined limiting position, for example no-load idling, or full-load wide-open position, and engages a corresponding stop (12, 14; 212, 214), the microprocessor provides a test or monitoring signal which algebraically differs from that which a command signal should have when the fuel control element is at the respective position. The test signal is changed, in linear steps, towards the condition at which an error signal within the servo loop becomes zero or null; the value of the test command signal is stored at that time and used as a compensation or added, algebraically, to the transduced command signal from the command control transducer (2), or interpolated with respect to the other limiting position to derive an interpolation characteristic, thereby modifying the transduced command signal, so that the actual position of the fuel supply control element will be that desired by the operator controlling the operator-controlled controller (1).
