The section objectives more particularly related to the proposed Research Fellowship activities are highlighted in bold in the above list. Interested candidates are highly encouraged to visit the ESA website www.esa.int Fields of activitiesresearch Experimental validation of advanced active microvibration mitigation strategies. Attaining high pointing stability performance is a critical objective for many current and future space missions. As lineofsight stability requirements get tighter, mechanical vibrations become one of the key performance limiting factors. Commonly termed microvibrations, these lowamplitude disturbances span a wide frequency range from few Hz up to 1 kHz and are produced by a variety of mechanical and electrical spacecraft systems. Microvibrations can propagate, through the structure of the spacecraft, towards the various optical or communication systems severely degrading their performance. It is critical for mission success to design adequate vibration isolation systems that can minimize their impact. Pure passive isolators, such as the ones based on elastomeric materials, are the current baseline for microvibration mitigation to dampen highfrequency perturbations. Yet, passive isolation methods are limited in the lower part of the microvibration range and can be insufficient in terms of isolation performance. In order to overcome the frequency limitations of a purely passive approach and achieve broadband vibration isolation, the proposed research will focus on the design of a complementary active control strategy that primarly targets the lower range of the frequency perturbations such as the ones introduced by reaction wheels. In order to precisely tune these control strategies and guarantee both compliance with the mission pointing stability requirements and also safeguard against potential uncertainties or faults, accurate dynamic models of the endtoend system must be obtained. Mathematical models that reflect both the driving physical phenomena as well as uncertainties present in the system will be established and validated along the project. These models will supplement nonlinear simulations and capture the complex dynamic interactions between the microvibration sources, the isolation system, the spacecraft structural dynamics and the optical payload system. With this knowledge, a second objective of the study is to demonstrate the capabilities of a common unified framework in which system design, robust controller synthesis, parametric sensitivity and worstcase analysis can be rigorously performed using a common set of wellestablished mathematical tools. These analytical tools provide strong stability and endtoend performance guarantees in the face of uncertainty without relying on timeconsuming Monte Carlo simulations. In a natural way, adaptive control solutions with guaranteed stability and performance margins will be obtained by design. Finally, the project will lead to the development of an advanced experimental testbed that will serve as a validation platform for future microvibration control and high pointing stability research activities. Research Programme Specifics The Research Fellowship programme of work would be the following YEAR 1. Detailed problem Formulation, Requirements Capture, Model Identification and Setup of the Simulation and Experimental Platforms, Preliminary Controller Synthesis a Development of the simulation environment SimMechanics capturing the relevant dynamics of the experimental platform b From the physical high fidelity E2E model perform the derivation of adequate analysis and synthesis models that capture model uncertainties using a linear fractional representation c Model identification, validation and uncertainty quantification based on experimental results shall be performed via an experimental system identification campaign d Definition of performance and robustness objectives based on the physical limitations of the system. e Setup of the IQC robust analysis framework to validate and verify a given control law. f Baseline controller synthesis, experimental validation and comparative analysis of a series of classical vibration control algorithms.
