  • Method for operating a fluid system and fluid system
    Patent number: 12540684
    Abstract: A method for operating a fluid system, which has a control device with a control functionality and a piezoelectric valve assembly that can be controlled by the control device. The method involves the following steps: providing a target working pressure at the working connection, measurement of the actual working pressure at the working connection by the pressure sensor, transmitting the measurement data to the control device and applying the algorithm to compare the actual working pressure with the target working pressure, activating the at least one integrator to integrate the control deviation of the control voltage (=offset voltage) after the actual working pressure is constant over a certain time period, and changing the control voltage as a function of the determined target/actual deviation taking into account the integrator operation.
