In WP1, a set of requirements was developed and defined to specify the requirements in terms of electrical, mechanical and software specifications. The requirements tabulated in Deliverable D1.1 are adjusted by the FloCoS consortium in close cooperation with the CS 2 LPA partners and the Topic Manager. In the middle of the project duration and coordinated with the activities in WP2, the system requirements were updated in order to take into account the findings in WP 1 and 2 and the updated actuator specifications.
For the fluidic actuator (ZNMF) system, drive and control hardware and software system was specified in the requirements working assumption document. This includes the power and performance requirements as well as the power supply and also interfaces and space constraints. Based on these specifications, an overall system design was developed and discussed. The system comprises actuators (piezoelectric), sensors, HV supply, data processing units (DPU) and wires. The main outcome of WP 2 is the functional design, that was completed for the amplifier board, MCU board, and electronic rack backplane board. Block diagrams were made to define the structure between all the functions.
In WP3, the system architecture was defined and the main components of the HV power supply system were designed. This included the definition of an updated overall system concept including the different parts of the system: HV-IC and PCB, U/ I-Monitoring system, I/O-System, HV-Supply system. The overall system concept was influenced by the design of the several subcomponents, which are developed with the different tasks in WP2 and 3. Therefore the work packages were carried out in parallel. Based on the overall system definition and also based on the specific requirements for the drives and control system, a block diagram was developed to define the overall signals routing between the electronics boards of the rack. In addition, the communication concept as well as the general GUI for the control software was designed. Based on these general concepts, the drive and control software for the high voltage supply system was developed. The communication is based on TCP/IP in order to ensure the ability to drive the system over higher distanced, e.g. in large scale wind tunnel facilities.
In WP4, the HW component purchasing and the HW assembly was performed. This includes the manufacturing and pre-test of the single components of the system (HV-IC and PCB, U/ I-Monitoring system, I/O-System, HV-Supply system) as well as the assembly of the components to the full system integrated in an rack-mounted and actively cooled housing.
In the testing WP (WP5), first measurement conducted by the CS LPA partners were analysed in order to support the activities in WP1 and WP2. After the final delivery of the HW was fully tested with dummy capacitances as well as real AFC HW.
In parallel to all the technical work packages, the management WP was carried out. The activities were the monitoring and communication within the consortium as well as the communication with the CS JU as well as the TM. In addition, reporting and dissemination and exploitation activities were carried out. Especially the challenging situation during COVID19 and its effect, made a confident management necessary.
