Description
The PETRA-IV Fast Orbit Feedback (FOFB) system will be a large-scale Multi-Input Multi-Output (MIMO) control system, utilizing 790 Beam Position Monitors (BPM) and 560 Fast Corrector Magnets (FCM) to maintain the desired orbit trajectory. Data acquisition and distribution will be managed across 16 supply areas and connected via an extended star network topology. This contribution focuses on system integration test setups while describing the Model-Based Design (MBD) methodologies that are being used for developing, verifying, and commissioning the complete system step by step. Integration of the components of such a large system must be systematic so that potential issues can be isolated and fixed efficiently. The setups will also be used for the characterization of sensors, actuators, and transmission lines. Subsystem identification is of utmost importance for a comprehensive understanding of the system dynamics, which will guide the design of appropriate filters and control strategies to ensure optimal orbit stabilization performance. The analysis will also precisely assess the overall system latency, which is critical for feedback bandwidth and stability.
