Embodiments of the present disclosure includes a method of calibrating a pump in a system to determine a minimum pump duty cycle needed. The system comprises a pump, a plurality of application lines downstream of the pump, and a flow control device in each application line. The method determines the minimum pump duty cycle to achieve total flow in the system, achieves a minimum pressure in the system, and ensures that the flow control device is not at or beyond a maximum open position.

A dynamic energy exchange platform is described that provides real time control of various system components by using regular sensors as well as sensorless actuators, resulting in an overall balance of energy for the entire system. A sensorless multi-parametric control solution may provide regular operation control, support control, and improvement control. The regular operation control comprises system control during normal operation. The support control comprises abnormal operation recovery control, and the improvement control allows potential system growth and/or controlling aging degradation. Embodiments of the disclosure encompass man-machine and machine-machine (or machine/material) interfaces with active points where energy exchange takes place.

A cooperative actuator system for active flow control, a vehicle comprising such cooperative actuator system, and a method for operating an actuator system for active flow control. The cooperative actuator system includes actuators, a control unit, and a data unit. The actuators are distributed along the surface in at least a first group and a second group downstream of the first group. The control unit is configured to control the actuators of the first group so that they form a first flow structure along the surface. The data unit is configured to provide data of the first flow structure. The control unit is further configured to control the actuators of the second group based on the data of the first flow structure, so that the actuators of the second group cooperatively interact with the first flow structure to form a second flow structure along the surface.

A servo control device includes a coarse-movement reference model unit calculating a coarse-movement model position by performing predetermined filter computation based on a position command; a coarse-movement follow-up control unit controlling the coarse-movement shaft motor such that a coarse-movement-shaft motor position follows the coarse-movement model position based on the coarse-movement-shaft motor position provided from the coarse-movement shaft motor and the coarse-movement model position; an integrated reference model unit calculating an integrated model position by performing predetermined filter computation based on a position command; and a fine-movement follow-up control unit controlling the fine-movement shaft motor such that a fine-movement-shaft motor position follows a fine-movement model position based on the fine-movement-shaft motor position provided from the fine-movement shaft motor and the fine-movement model position obtained from the integrated model position and the coarse-movement model position.
