Network-efficient isolation environment redistribution is described. In one example, network communications are surveyed among isolation environments, such as virtual machines (VMs) and containers, hosted on a cluster.

Further, as a function of the clutch signal, the regulating device generates a preliminary target value signal for the pressure and a time derivative of the preliminary target value signal is generated as a movement signal, and a pilot control generates a pilot control signal as a function of the movement signal, and the preliminary target value signal and the pilot control signal are combined to give a final actuating value signal for the pressure.
US11326656B2 Controlling an actuator of an actuator unit of a motor vehicle
A method for controlling an actuator of an actuator unit of a motor vehicle includes detecting desired activation of the actuator, detecting whether a currently present operating state of the motor vehicle is a first operating state or a second operating state, selecting either a first control routine upon detecting the first operating state or a second control routine upon detecting the second operating state, and actuating the drive motor with the selected first control routine or second control routine. A drive motor of the actuator unit is controlled depending on the operating state of the motor vehicle. In the first operating state, an actuation of the actuator occurs according to the first control routine with high dynamics of the drive motor, and in the second operating state, the actuation of the actuator occurs according to the second control routine with adjusted dynamics of the drive motor.
