摘要： A capacitive control element is charged with a defined charging voltage Uc. From a stored mapping KF, the instantaneous control element capacitance Cp is determined from the charge voltage Uc and a control element voltage Up. In addition, energy E supplied to the control element is determined from the charge voltage Uc and the control element capacitance Cp. According to a deviation of energy E fed to the control element from a stipulated amount of energy Ev, the charge voltage Uc for a next drive process of the control element is regulated. The same process occurs for additional control elements.

摘要： A method of driving at least one capacitive actuator with a charge voltage. From a charge quantity .DELTA.Q supplied to the actuator and from the actuator voltage U.sub.p applied to the actuator after the charging operation is terminated, the actuator capacitance is calculated by the equation C.sub.p =.DELTA.Q/U.sub.p. From these values, the energy E.sub.actual =0.5*C.sub.p *U.sub.p.sup.2 =0.5*.DELTA.Q*U.sub.p is calculated. The charge voltage is regulated such that the energy actually supplied is equivalent to a specified desired value.

摘要： A method for controlling a capacitive actuator includes the steps of determining an energy applied to an actuator, measuring an actuator voltage present at the actuator, and inferring a functional state of the actuator by using the energy and the actuator voltage. A capacitive actuator is fed energy and the actuator voltage present at the actuator is measured. The energy and the comparison of the actuator voltage with reference values are used to infer a functional state, for example, either faults or correct function of the actuator or injection valve. Furthermore, the actuator voltage is used to infer an actuator stroke. The method is based on actuator characteristics. The invention also includes a circuit for controlling a capacitive actuator having a driving circuit with a main switch, a charging capacitor, a first series circuit including an oscillating coil, an auxiliary switch, and a second series circuit having a discharging switch, a charging switch, and a diode to be connected to the actuator, and a control device having a program and a family of characteristics with actuator characteristics defining characteristic curves, reference values, and correction factors.
